I have found that Char.IsLetter() returns True for the masculine ordinal character, described at  The Char.GetUnicodeCategory() function reports it is a LowercaseLetter, but I would think it should be reported as a symbol.  I have tested this in both .NET 4.0 and .NET 4.5.  

Of course, this could be "by design"; I'll let you respond.

Thank you for your feedback. This issue is actually by-design.

We are following the Unicode standard. It defined Lo (Other_Letter) as lowercase.
