In rebasing this to develop include 08c0721

[manics]

All Java \u escapes have been removed, $ git grep '\\u' -- '*java' returns nothing, builds fine.

$ git grep -A16 '<javac' -- '*.xml'shows two files with javac tasks that don't have the encoding parameter, though don't know if it's required here:
components/insight/build/app.xml
components/insight/build/test.xml

[manics]

Also it looks like our code is free of non-unicode chars (using https://gist.github.com/manics/4707338)

Thanks, I hadn't actually noticed Insight's app.xml and test.xml files.

Builds fine. I think this is good to merge, unless the separate whitespace commit is a must instead of a "next time".

@manics: definitely more a "next time" sort of thing.

Otherwise, UTF-8 changes all look fine. Holding off until Monday for comments from @jburel.

Everything looks fine. Merging
