[Mono-dev] Error Normalizing Arabic Strings

[Atsushi Eno]

Hi Tom,

Thanks. I'll have a look next week.

I'm not passionate to fix every unicode normalization issue unless I can 
fully commit this
area. .NET is not very excellent on Unicode compliant normalization (it 
fails much more
than us according to normalization tests). Crashers like this are no 
good though.
