Like working with integer arrays. Just some notes: Often you need to replace ASCII characters like new lines, spaces or semicolon. These can be replaced in UTF-8/UTF-16 as easily. If you want to replace non ASCII characters for example to normalize diacritical characters then even in UCS-2/UCS-4 you have to replace several codepoints with one. UCS-2 does not matter for the RTL, which must work with the full Unicode range. And UCS-4 is a waste of space for big texts. How many functions have you written that replaces characters in an UTF-8/UTF-16 string with different size characters?
