This problem can also be reproduced with English as the current language.
Just pick a character between 128 and 256 to include in the name of the build directory.
For example, buildñ, and run cmake in there pointing to any source tree.

For me, the Visual Studio 9 2008 generator works fine and the project file reports an encoding of Windows-1252.
It fails with the the Visual Studio 10 generator where the project file reports a utf-8 encoding, but it really isn't utf-8.
So I get errors like this:
 C:\...\cmake\buildñ\CMakeFiles\CMakeTmp\cmTryCompileExec926
91608.vcxproj(56,110):
 error MSB4025: The project file could not be loaded.  Invalid character in
 the given encoding.  Line 56, position 110.

Modifying cmVisualStudio10TargetGenerator.cxx to set the encoding of the visual studio file to Windows-1252 instead of utf-8 fixes the problem for me.
