Notes to Callers:
As explained in Best Practices for Using Strings in the .NET Framework, we recommend that you avoid calling character-casing and string-casing methods that substitute default values. Instead, you should call methods that require parameters to be explicitly specified. To convert a character to uppercase by using the casing conventions of the current culture, call the ToUpper(Char, CultureInfo^) method overload with a value of CultureInfo::CurrentCulture for its culture parameter.
