I think it is very important that the encoding is handled consistently by all build tools. I wanted to fix this for a while now because too many times I had to specify UTF-8 explicitly and the build system tried to use ASCII. UTF-8 is the de-facto standard encoding in Debian and should be a first class citizen in Debian Java too. Thus said I don't want to force this on you. Just give me some hints where I have to look in the javahelper package and I experiment with the available options myself. >> Maybe the logic should be: IF NOT EXIST property encoding in pom.xml or >> (IF EXIST debian/maven.properties AND debian/maven.properties CONTAINS >> STRING project.build.sourceEncoding) SET encoding to UTF-8 > > For Maven projects this will fix nothing.

Lately I haven't discovered any issues in Maven, so the above might be true. Though I still don't understand why there is an ASCII fallback in Maven and maybe other Java tools. It appears to be completely anachronistic.
