() does not handle surrogate characters appropriately.

In Microsoft's implementation of .NET, the result of
System.Globalization.CharUnicodeInfo.GetUnicodeCategory("\uD800\uDF80", 0);
is OtherLetter, while Mono returns Surrogate. The reason for this is that while
\uD800 and \uDF80 each belong to the unicode category Surrogate, together, they
form the surrogate pair for UGARITIC LETTER ALPA, which has the unicode
category OtherLetter.
>From what I can tell, Mono's implementation of GetUnicodeCategory never does
any special handling for surrogate pairs.
Reproducible: Always
Steps to Reproduce:
1. Call System.Globalization.CharUnicodeInfo.GetUnicodeCategory("\uD800\uDF80",
0);
2.
3.
Actual Results:
UnicodeCateogry.Surrogate is returned.
Expected Results:
UnicodeCategory.OtherLetter should be returned.
