Why Scala on Mac fails when run in unicode directory

I am attempting to simply compile a helloworld scala file from within a directory named using unicode characters but the scala compiler fails to run. It succeeds when I change directory's out the unicode named folder.
Detail
Given a classic Helloworld.scala class such as the one below
that is located in the directory:
/Users/me/Dev/Company/𝔘𝔫𝔦𝔠𝔬𝔡𝔢/code_folder
I am unable to run scalac on the code if my current directory is in code_folder which is the root directory for the Helloworld.scala. When I change directories out of the folder with the unicode name /𝔘𝔫𝔦𝔠𝔬𝔡𝔢, the compiler works just fine on the same code. So it would seem that scalac doesnt work when attempting to compile code while in a folder with unicode characters.
Why is that? Is this a system error? An unparsed unicode error between the OS starting the scalac process?
object Main{
def main(args: Array[String]): Unit = {
println("Hello world")
}
}
I expected a compiled file. The error I get is this

Not really a solution, but some piece of information:
I set up my folder this way:
/home/nicolas/Private/𝔘𝔫𝔦𝔠𝔬𝔡𝔢/
When the ClassLoader tries to load the classes of your project it makes a list of paths where to lookup classes as a list of URLClassPath
Now when the code goes on and it tries to parse these paths, it calls sun.net.www.ParseUtil.decode()
When I put a breakpoint in here, I can see that the path for our class is:
/home/nicolas/Private/%ed%a0%b5%ed%b4%98%ed%a0%b5%ed%b4%ab%ed%a0%b5%ed%b4%a6%ed%a0%b5%ed%b4%a0%ed%a0%b5%ed%b4%ac%ed%a0%b5%ed%b4%a1%ed%a0%b5%ed%b4%a2/target/scala-2.12/classes/
so it somehow translated 𝔘𝔫𝔦𝔠𝔬𝔡𝔢 into a percent encoded string : %ed%a0%b5%ed%b4%98%ed%a0%b5%ed%b4%ab%ed%a0%b5%ed%b4%a6%ed%a0%b5%ed%b4%a0%ed%a0%b5%ed%b4%ac%ed%a0%b5%ed%b4%a1%ed%a0%b5%ed%b4%a2
This in turn creates a CharsetDecoder for UTF-8:
CharsetDecoder dec = ThreadLocalCoders.decoderFor("UTF-8")
.onMalformedInput(CodingErrorAction.REPORT)
.onUnmappableCharacter(CodingErrorAction.REPORT);
and tries to decode the above url but it fails and that is why the classes can't be loaded.
Now if I go here https://www.branah.com/unicode-converter and tries to convert 𝔘𝔫𝔦𝔠𝔬𝔡𝔢 to a % encoded string, it gives me
%f0%9d%94%98%f0%9d%94%ab%f0%9d%94%a6%f0%9d%94%a0%f0%9d%94%ac%f0%9d%94%a1%f0%9d%94%a2
And if when I debug, I change the url using this encoded string value, ie
/home/nicolas/Private/%f0%9d%94%98%f0%9d%94%ab%f0%9d%94%a6%f0%9d%94%a0%f0%9d%94%ac%f0%9d%94%a1%f0%9d%94%a2/target/scala-2.12/classes/
Then it parses it properly and keeps going.
So I don't know where it gets that %ed%a0%b5%ed%b4%98%ed%a0%b5%ed%b4%ab%ed%a0%b5%ed%b4%a6%ed%a0%b5%ed%b4%a0%ed%a0%b5%ed%b4%ac%ed%a0%b5%ed%b4%a1%ed%a0%b5%ed%b4%a2
The interesting thing is that if I use the same website and try to convert back %ed%a0%b5%ed%b4%98%ed%a0%b5%ed%b4%ab%ed%a0%b5%ed%b4%a6%ed%a0%b5%ed%b4%a0%ed%a0%b5%ed%b4%ac%ed%a0%b5%ed%b4%a1%ed%a0%b5%ed%b4%a2 then I also get 𝔘𝔫𝔦𝔠𝔬𝔡𝔢
So I am a bit confused

saved .pb file(created using darkflow) not loading in java

I used the following command to create a .pb file:
flow --model ../YOLOv2/alexeyAB_darknet/darknet-master/cfg/yolov2-dppedestrian.cfg --load ../YOLOv2/alexeyAB_darknet/darknet-master/backup/yolov2-dppedestrian_33900.weights --savepb
Although the model was created successfully, when I load it into my java tensorflow application, I get the following error:
Exception in thread "Thread-9" org.tensorflow.TensorFlowException: Could not find meta graph def matching supplied tags: { serve }. To inspect available tag-sets in the SavedModel, please use the SavedModel CLI: saved_model_cli
The problem is in the second line of code:
String model_path = "/home/adisys/Desktop/cloudiV2/models/yolo_pedestrian/saved_model";
SavedModelBundle model = SavedModelBundle.load(model_path, "serve");
I tried digging deep and found this link:
Can not load pb file in tensorflow serving
Following the link I ran the following command:
saved_model_cli show --dir saved_model/
The output is as follows:
/home/adisys/anaconda3/lib/python3.6/site-packages/h5py/init.py:34: FutureWarning: Conversion of the second argument of issubdtype from float to np.floating is deprecated. In future, it will be treated as np.float64 == np.dtype(float).type. from ._conv import register_converters as _register_converters
The given SavedModel contains the following tag-sets:
As can be seen, there were no tag-sets displayed.
What could be the issue?

I just saw your post, I'm sure the problem has solved itself now, but I'm leaving the comment for others working with darkflow. The command --savepb needs to be assigned as --savepb True

Internal Action was not loaded Error: java.lang.ClassNotFoundException

I am trying to run an implementation a jason code that is using some Internal Actions. The interpreter is showing that it was not possible to find the "java" code of the internal action, as showed:
Server running on http://191.36.8.42:3272

[peleus] Adding belief clear(table)
This mas2j file is as following:
MAS peleus {
infrastructure: Centralised
agents:
peleus;
}
Part of agent code (written by Felipe Meneguzzi) is showed bellow:
//The next line is line 28
+des(Goals) : true
<- org.soton.peleus.act.plan(Goals);
!checkGoals(Goals);
.print("Goals ",Goals," were satisfied").
+!checkGoals([]) : true <- true.
//The next line is line 40
+!checkGoals([H|T]) : true
<- .print("Checking ", H);
org.soton.peleus.act.isTrue(H);
!checkGoals(T).
I guess it is about the folder structure, how to set up Jason to search for java files in specific locations?
The folders structure is like this:
Peleus\src\org\soton\peleus for java files
Peleus\examples for mas2j and asl tested project

It all depends on how you are executing the application.
If you are using java, the CLASSPATH should be defined to include the missing classes.
if you are using jason script (that uses Ant), the .mas2j file should include the class path as well.
More on that in the FAQ. Notice that CLASSPATH is where .class files are found, not .java source code files. The error regards a missing class, not a missing source code.

Scala: no corresponding Java Class found

While Compiling an Scala 2.10 Project, I got an error I cannot even understand
java.lang.NoClassDefFoundError: no Java class corresponding to MongoPersistable.this.type found
at scala.reflect.runtime.JavaMirrors$JavaMirror.typeToJavaClass(JavaMirrors.scala:1218) ~[scala-reflect-2.10.0.jar:na]

at scala.reflect.runtime.JavaMirrors$JavaMirror.runtimeClass(JavaMirrors.scala:65) ~[scala-reflect-2.10.0.jar:na]
...
How is this even possible to get such a error message if the code got well in eclipse in first place?
Following line of Code produces this error:
trait MongoPersistable {
def save() {
val dao : MongoDAO[MongoPersistable.this.type] = MongoDAO[this.type];
....
I would upload more code if I know where to search

XML validation error message always display

I am a Java developer. I'm working with a legacy system which is using Strtus1.2.9. After I added some jar file to this system and started the Tomcat, some error message display in the console. It seems like some of old xml file can not pass the parse. The tracback is like the following:
