I don't see that the proposed \u{...} notation fixes any limitation. Its only advantage would be slightly better readability opposed to inserting the desired UTF-8 byte sequences as octal or hexadecimal escapes. For instance, all of the following would print Ä (in an UTF-8 context): echo "\u{00C4}"; echo "\xC3\x84"; echo "\303\204"; -- Christoph M. Becker
