Some strings found in the wild cause String.Normalize(NormalizationForm.FormKC)
to throw an exception.

Actual Results:
System.SystemException: Internal error: should not happen.
at Mono.Globalization.Unicode.Normalization.Combine
(System.Text.StringBuilder sb, Int32 start, Int32 checkType) [0x00000]
at Mono.Globalization.Unicode.Normalization.Combine (System.String source,
Int32 start, Int32 checkType) [0x00000]
at Mono.Globalization.Unicode.Normalization.Compose (System.String source,
Int32 checkType) [0x00000]
at Mono.Globalization.Unicode.Normalization.Normalize (System.String source,
Int32 type) [0x00000]
at System.String.Normalize (NormalizationForm form) [0x00000]
at normalize.MainClass.Main () [0x0006b] in /tmp/normalize/Main.cs:25
Expected Results:
I have no idea, but at least it shouldn't throw exceptions, or the exceptions
should be documented.
The same programme doesn't crash on .NET 3.5sp1
