string s = "h";
s = s.ToUpper();
returns "H".
string s = "8";
s = s.ToUpper();
returns "8"
Should this not return "*"?
string s = h; s = s.ToUpper(); returns H . string s = 8;

No, it shouldn’t.
ToUpper()doesn’t meanWithShiftKeyOnAnInternationalASCIIKeyboard(). There isn’t an uppercase 8, as 8 is a number, not a letter.Of course, this is a gross over-simplification (being a number alone doesn’t automatically make a certain character in a character set caseless), but it’s likely what you’re asking for anyway so I’ll leave it at that.
