My C# project saves files and creates folders with the extended ASCII character "²" (superscript 2). Is this safe to work with internationally? Is this something that could cause any issues with the .NET libraries or Windows functions?
Starting windows NT (?) filenames are always unicode. so there shouldn't be a problem.
Things do get hairy when you start using alternative space characters, transliterated characters or characters which should have a bidirectional context but that is not the case with the superscript 2
