I want to check whether a character is in Extended ASCII range (0-255).
So I guess you mean you want to know if a char value is greater than 127, since below that its not extended ascii.
Iterating over the string char by char as Mark suggested is not very efficient, specially for larger strings.
You can use QRegExp to match all char above 127 with \\0x80-\\0x255.
