May I suggest that you create your own fork of PHP and leave the rest of u
which deals with them.
Thereby increasing the complexity of the PHP engine - which means more bugs and
slower execution. It also makes it harder for the user to understand: they need
to get their heads round the corner cases.

If you think that it is a bad idea, please update the RFC to say why this is a
bad idea and so why it is not going to happen - for now.
It would be nice since a code point is just a big number without any really
obvious
meaning, but a name makes for greater
ently reminicent of C to be helpful of those of us
with that background.
$# if PHP_VERSION_ID > 50500

Without wanting to make it too complicated, it might be nice to allow a 'set'
