Hmm, curious to know what problem you are facing with the unicode symbols. Java compiler and all Java tools support Unicode since a long time now.

Hmm, your javac is defaulting to ASCII encoding. Can you check if this works: add -Dfile.encoding=utf-8 to your ANT_OPTS environment variable and then run ant again.

If that works we can try to modify build.xml to permanently set the encoding.

Hello hrj, yes adding -Dfile.encoding=utf-8 to ANT_OPTS works fine.
