i am stucked in this crictical problem and i don't know how to cater this. I sometimes receive this String ⒗⒕►☻☺ and sometimes these are non US-ASCII characters. These ⒗⒕►☻☺ characters are replaced by ? and is represented as it is. I sometime receive this character too. These characters are in ANSI list but i want to receive only US-ASCII. Please help me out that how to identify these characters in the string.
