How to replace \xA0 characters in an NSString

问题

The following code doesn't work:

NSString *importText = [textView.string stringByReplacingOccurrencesOfString:@"\xA0\xA0"
 withString:@" "];

Compiler claims: "Input conversion stopped due to an input byte that don't belong to the input code set UTF8"

回答1:

Try the Unicode escape sequence \u00a0.
