Perhaps I am missing something, but since NSString handles Unicode fine,
just use either NSString's
stringByReplacingOccurrencesOfString:withString: or NSMutableString's
replaceOccurrencesOfString:withString:options:range: ?
This makes for less work and more readable code since you should be able
to literally paste the "foreign" characters into your search string and
not have to fuss around with character codes.
Of course, if your input contains the problem characters in multiple
underlying representations (say, from different languages), this
complicates matters. Such a situation happened to me a while back,
wherein an application on the system and the terminal had different
notions of how to store accented characters. Suffice it to say this led
to much hair pulling when it came time to do source code management
("file X is been added, file X has been removed").
