Another line needs to be added after this, which would be

case '\u0085':

This is because it is recognised as a newline character in C# (see here), which cannot be in literal strings.
If the CSharpCodeGenerator class was used to make code with a string in it that has U+0085 in it, it would generate invalid C# code.
NB: this is also an issue on the .NET Framework (see here)

I would like to implement this change, thanks!
