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";
