@mymagicpower I don't think this can be fixed, it's a bug in Java System.load() function.

I tried the following code, and it failed with Chinese file path:

Path file = Paths.get("asmjit.dll");

String path = file.toAbsolutePath().toString();

System.out.println("Loading file: " + path);

System.load(path);

System.out.println("Loaded file: " + path);



file = Paths.get("张三\\asmjit.dll");

path = file.toAbsolutePath().toString();

System.out.println("Loading file: " + path);

System.load(path);

System.out.println("Loaded file: " + path);


Loading file: C:\source\test\asmjit.dll
Loaded file: C:\source\test\asmjit.dll
Loading file: C:\source\test\张三\asmjit.dll

@frankfliu can we add a special character check before System.load command? This will fail regardless of System right? It will provide a better insight on what's going on

[frankfliu]

We can add a warning if cache directory contains non-ASCII chars. But non-ASCII chars not necessary will always fail.

The problem is CJK Windows native charset is not set to UTF-8, it usually be "GBK", "Shitf-JIS" etc. For most of western language, non-ASCII chars should still work.
