Hello,

GetCount() returns 7 for the string "lub�ck" Surprised

I see only 6 characters. Where is the trick?
I guess '�' is counted twice, but how can I know how many characters are really there in a string?

GetCount or GetLength returns a number of _bytes_ in string.

When it is UTF-8 encoded, this is more than number of characters it represents.

Good way to convert is

.ToWString().GetCount()

or you can use "utf8len" function too..

(Anyway, thinking about it, perhaps I shall add "GetCharCount()" method to String...).
