           Summary: string.Normalize() frequently produces incorrect
                    output
    Classification: Mono
           Product: Mono: Class Libraries
           Version: SVN
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: CORLIB
        AssignedTo: mono-bugs at lists.ximian.com

A number of examples could be provided. Here are a couple, taken from
http://unicode.org/reports/tr15/

"\u212B" -- Form D is "\u0041\u030A", but Mono provides "\u00C5" (Taken from
Figure 3. Singletons)
"\u1E69" -- Form D is "\u0073\u0323\u0307" but Mono provides "\u1E63\u0307"
(Taken from Figure 5. Multiple Combining Marks)

Additionally, I believe:

Form D of "\u1e4e" should be "\u004f\u0303\u0308", but Mono provides
"\u00d5\u0308"--incidentally, you get "\u004f\u0303\u0308" if you try to
normalize "\u00d5\u0308".

Form D of "\u1e2f" should be "\u0069\u0308\u0301", but Mono provides
"\u00ef\u0301"--this also comes out correctly if doubly-normalized.

Form C of "\u0041\u030a\u0061\u030a" should be "\00c5\00e5" but Mono provides
"\u212B\00e5"--however, Mono correctly reports form C of "\u0041\u030a" as
"\u00c5".

Reproducible: Always

Steps to Reproduce:
1. Compile/run code that Normalizes the example string
2.
3.
Actual Results:  
Normalize() frequently produces incorrect results.

Expected Results:  
Normalize should provide correct results.
