I appreciate all that you said. I didn't expect that UTF-16 was so uncommon in non-Windows
OSes. A large number of dev tools that I work with on Windows, especially the Microsoft tools
default to creating UTF-16 files.  

I disagree with your "can be converted without data loss". If you need UTF-16 then you need
it. Also, if you are working in an international team and you have developers with other language
Oss which have different code pages then what you see when you look at a UTF-8 file might
be different than what I see. 

So, when I say "I'm surprised" I only say that with the knowledge that the internet has made
the world very flat and I'm sure there is much more collaboration amoungs people that use
different languages and work on apps that need to deal with international languages, etc.
I'm not dissing the devs in any way.

If I knew how to I would. While I work with C# and I'm sure C is similar it is probably much
different. If a svn dev would mentor me through it, and perhaps tell me what modules would
need to be modified I would be happy to take a whack at it.
