StrfName's String property uses Marshal.PtrToStringUni to cast the recieved string to a C# string, passing it the string_len from the StrfName structure of FreeType. According to FreeType's documentation, string_len represents the length of string in bytes, while PtrToStringUni's len parameter recieves number of Unicode characters to copy, each being 2 bytes. This results in StrfName's Strings being longer than they really are.
Tested this change on some Windows embedded fonts in Win7, and the fields now get fetched correctly.
