If I read the docs correctly, then the new Visual Studio 2005 CRT will
actually look for BOMs if a file is opened in text mode, and silently do
Unicode->ANSI conversion as needed - yuck!

<http://msdn2.microsoft.com/en-us/library/yeby3zcb(VS.80).aspx>

This will be a problem for UTF-8 files read as text, which is how the
config files are de-facto read (you may recall the thread with the
Chinese mod_dav_svn user with an authz problem).

Letting the CRT convert UTF-8 -> ANSI would be a dangerous thing.
Another good reason for using binary!
