Cannot read folders, receive only spinning cursor

[Omar Willey]

Hi, I'm having some strange errors with VietOCR on ArchLinux. I start the program using

./ocr

I try to open a new file. But VietOCR won't read my Documents folder. I get the following:

Exception in thread "Basic L&F File Loading Thread" java.nio.file.InvalidPathException: Malformed input or input contains unmappable characters: /.../Downloads/Docs of Sort/????????????.html

It just gives me a spinning cursor, until I cancel. I get this error with several different folders.

In each case the error is the same. It happens with files in different languages, not just English.

This does NOT happen if I start with

java -jar VietOCR.jar

But if I start with the JAR file, I sometimes run into Out of Memory or Java Heap errors. So I like to start with the OCR executable.

Suggestions? I am on ArchLinux 6.1.12-arch1-1 with openjdk 19.0.2 2023-01-17, OpenJDK Runtime Environment (build 19.0.2+7), and OpenJDK 64-Bit Server VM (build 19.0.2+7, mixed mode).

It appears that the program cannot read the specified file because of the file name or path contains Unicode characters. At the beginning of the script, export LC_ALL=C was set, which might have interfered with that.

You can either remove that line or run at the command line with options to give more heap memory for Java program startup.

java -Xms128m -Xmx2048m -jar VietOCR.jar
