Android 2.3.3 / Java
I have a String[] that is assigned with static values containing special characters like √x²+y² and so on. When I try to save the file, i get the following error, please refer to the image below. How do I get over this? Assigning these values statically is a must. Is there a way I can change the encoding of the java file and yet have other things remain the same.
Here is how I am trying to assign the values ::: For example...
commandNames = new String[] {"√x²+y²","√x²+y²","√x²+y²"};
Your file have utf-8 characters.There is no issue by saving it as Save as UTF-8
Click that saveasUTF8 button
or
Change your file properties by
Windows > Preferences > General > Content Types, set UTF-8 as the
default encoding for all content types.
if you are using this in jsp page then include meta tag in header of your jsp page and
specify your content format in meta tag
and if it are using it in servlet then set response type as
response.setContentType("");

I have the following code in my JSP
... <%
out.println(request.getAttribute("textFromDB")); %> ...
When the JSP is called it just prints question marks (????..) instead of the actual text stored in a MySQL database which is not in English. What can I do to make it display the text correctly. I tried to change the charset and pageEncoding to UTF-8 but it didn't help.
Isn't encoding nice? Unfortunately it's hard to tell where it gets wrong: Your database might store in another character set than UTF-8. Or your database driver might be configured to work in another encoding. Or your server defaults to another one. Or your HTTP connection assumes different encoding and your charset change comes too late.
You'll have to go through all those layers - and keep in mind that everything might look fine and it's been the long-past write-operations to your database that already messed up the data beyond repair.
System.out.println(this.request.getHeader("Content-Encoding")); //check the content type
String data = new String(this.request.getParameter("data").getBytes("ISO-8859-1"), "UTF-8"); //this way it is encoded to byte and then to a string
if the above method didnt work you might wanna check with the database
if it encode characters to "UTF-8"
or
you can configure URIEncoding="UTF-8" in your tomcat setup and just (request.getAttribute("textFromDB")); do the rest.
First time use FreeMarker on JAVA project and stack on configure the chinese character.
I tried a lot of examples to fix the code like below, but it still not able to make it.
// Free-marker configuration object
Configuration conf = new Configuration();
conf.setTemplateLoader(new ClassTemplateLoader(getClass(), "/"));
conf.setLocale(Locale.CHINA);
conf.setDefaultEncoding("UTF-8");
// Load template from source folder
Template template = conf.getTemplate(templatePath);
template.setEncoding("UTF-8");
// Get Free-Marker output value
Writer output = new StringWriter();
template.process(input, output);
// Map Email Full Content
EmailNotification email = new EmailNotification();
email.setSubject(subject);
.......
Saw some example request to make changes on the freemarker.properties but i have no this file. I just import the .jar file and use it.
Kindly advise what should i do to make it display chinese character.
What exactly is the problem?
Anyway, cfg.setDefaultEncoding("UTF-8"); should be enough, assuming your template files are indeed in UTF-8. But, another place where you have to ensure proper encoding is when you convert the the template output back to "binary" from UNICODE text. So FreeMarker sends its output into a Writer, so everything is UNICODE so far, but then you will have an OutputStreamWriter or something like that, and that has to use charset (UTF-8 probably) that can encode Chinese characters.
You need to change your file encoding of your .ftl template files by saving over them in your IDE or notepad, and changing the encoding in the save dialog.
There should be an Encoding dropdown at the bottom of the save dialog.
I want to save special character (UTF-8) in java.
In my JSF page I am setting string value in model
<h:inputTextarea id="que" value="#{dataModel.question}"/>
When I am going to fetch that String in my java controller that time this give
different character eg. I have sentence like ΔLMN ≠ΔXYZ when I am printing the value
in controller that time it prints like ΔLMN ≠ΔXYZ.
In my project I am fetch the value from XML file and write the same value in XML like
option.addContent(new CDATA(new String(this.launchModel.getQuestionList().get(i).getOptionList().get(k).getOption().getBytes("UTF-8"), "UTF-8")));
How to sovle this problem..I am trting my side..
The problem I'm trying to fix is this:
Users of our application are copy/pasting characters from windows-related docs like Word for instance, and our application is not recognizing single and double quotes or bullets.
These are the steps I've taken so far to get this data into UTF format:
inside servers.xml, in Connector tag, I added the attribute URIEncoding="UTF-8".
in the bean charged with storing the input, I created a byte[] and passed in String holding inputNote text, then converted it to UTF-8. Then passed the UTF-8 converted String back to inputNoteText String. Please see directly below for condensed code on this.
byte[] bytesInUTF8inputNoteText = inputNoteText.getBytes("UTF-8");
inputNoteText = new String(bytesInUTF8inputNoteText, "UTF-8");
this.var = inputNoteText;
In the variable-setter charged with holding the result from the db query:
setNoteText(noteText) to convert the note data coming from database query into bytes in UTF8 format, then converted it back into a String and set it to String noteText property. Also below.
public void setNoteText(String noteText) throws UnsupportedEncodingException {
byte[] bytesInUTF8inputNoteText = noteText.getBytes("UTF-8");
String noteTextUTF8 = new String(bytesInUTF8inputNoteText, "UTF-8");
this.noteText = noteTextUTF8;}
In SQL Server I changed the data type from text to nvarchar(MAX) to store the data in Unicode, even though that is a different type of Unicode.
What I see when I copy/paste from a MS Word doc into our JSF input textbox:
In Eclipse if I set a watch on the property in the bean, once the data in that String property has been converted into UTF-8, all characters are in UTF-8 format. When I post to to SQL Server the string of data held in nvarchar(max) datatype shows all characters in UTF-8 format correctly. Then when the resultSet is returned and the holding property is populated with the String returned from the db query, it also shows as all being correctly formatted in UTF-8....BUT,...somewhere in between the correct string value that's sitting in the property that's tied into the JSF page and the JSF page, 1.2 by the way, the value is being unformatted so that I see question marks where I should see single/double quotes and bullet points. I hope that someone has run into this type of issue before and can shed some light on what I need to do to fix this. Seems kind of like a JSF bug, thanks in advance for your input!!
try this
String noteText = new String (noteText.getBytes ("iso-8859-1"), "UTF-8");
When you copy paste from windows documents, the encoding format is not UTF-8 but [Windows-1252] (http://en.wikipedia.org/wiki/Windows-1252). Note the cells marked in thick green borders. These chars DONT map to UTF-8 charset and so you will have to use Windows-1252 encoding while reading.
I have a webpage that is encoded (through its header) as WIN-1255.
A Java program creates text string that are automatically embedded in the page. The problem is that the original strings are encoded in UTF-8, thus creating a Gibberish text field in the page.
Unfortunately, I can not change the page encoding - it's required by a customer propriety system.
Any ideas?
UPDATE:
The page I'm creating is an RSS feed that needs to be set to WIN-1255, showing information taken from another feed that is encoded in UTF-8.
SECOND UPDATE:
Thanks for all the responses. I've managed to convert th string, and yet, Gibberish. Problem was that XML encoding should be set in addition to the header encoding.

To the point, you need to set the encoding of the response writer. With only a response header you're basically only instructing the client application which encoding to use to interpret/display the page. This ain't going to work if the response itself is written with a different encoding.
The context where you have this problem is entirely unclear (please elaborate about it as well in future problems like this), so here are several solutions:
If it is JSP, you need to set the following in top of JSP to set the response encoding:
<%# page pageEncoding="WIN-1255" %>
If it is Servlet, you need to set the following before any first flush to set the response encoding:
response.setCharacterEncoding("WIN-1255");
Both by the way automagically implicitly set the Content-Type response header with a charset parameter to instruct the client to use the same encoding to interpret/display the page. Also see this article for more information.
If it is a homegrown application which relies on the basic java.net and/or java.io API's, then you need to write the characters through an OutputStreamWriter which is constructed using the constructor taking 2 arguments wherein you can specify the encoding:
Writer writer = new OutputStreamWriter(someOutputStream, "WIN-1255");
Assuming you have control of the original (properly represented) strings, and simply need to output them in win-1255:
import java.nio.charset.*;
import java.nio.*;
Charset win1255 = Charset.forName("windows-1255");
ByteBuffer bb = win1255.encode(someString);
byte[] ba = new byte[bb.limit()];
Then, simply write the contents of ba at the appropriate place.
EDIT: What you do with ba depends on your environment. For instance, if you're using servlets, you might do:
ServletOutputStream os = ...
os.write(ba);
We also should not overlook the possible approach of calling setContentType("text/html; charset=windows-1255") (setContentType), then using getWriter normally. You did not make completely clear if windows-1255 was being set in a meta tag or in the HTTP response header.
You clarified that you have a UTF-8 file that you need to decode. If you're not already decoding the UTF-8 strings properly, this should no big deal. Just look at InputStreamReader(someInputStream, Charset.forName("utf-8"))
What's embedding the data in the page? Either it should read it as text (in UTF-8) and then write it out again in the web page's encoding (Win-1255) or you should change the Java program to create the files (or whatever) in Win-1255 to start with.
If you can give more details about how the system works (what's generating the web page? How does it interact with the Java program?) then it will make things a lot clearer.
The page I'm creating is an RSS feed that needs to be set to WIN-1255, showing information taken from another feed that is encoded in UTF-8.
In this case, use a parser to load the UTF-8 XML. This should correctly decode the data to UTF-16 character data (Java Strings are always UTF-16). Your output mechanism should encode from UTF-16 to Windows-1255.
byte[] originalUtf8;//Here input
//utf-8 to java String:
String internal = new String(originalUtf8,Charset.forName("utf-8");
//java string to w1255 String
byte[] win1255 = internal.getBytes(Charset.forName("cp1255"));
//Here output
