Re: Building for windows. Again.



I can see the problem now from a local test.

Hmm i'm a bit confused. The JNI code uses GetStringUTFChars calls [1]
for all char * arguments going from Java to C, which is an array of
bytes representing the string in modified UTF-8 encoding. Is this OK?
The other option is to use GetStringChars which is unicode...
