Hi Hugo,

Subversion only supports Unicode it if is encoded as UTF-8.

Unicode represented in encodings other than UTF-8 is usually treated
like a binary file. Fixing this would be a major effort.

If you convert files you want to use with 'svn patch' to UTF-8, then
things should "just work". Note that conversion between UTF-8 and UTF-16
is generally lossless, so in the worst case this would add extra (but
nonetheless inconvenient) conversion steps to your workflow.
