It was fully my intention to allow however many leading zeros you like, and whatever capitalisation you like. ------------------------------------------------------------------------ [2016-03-08 21:19:17] yohgaki@php.net However, ES6 seems to have the same spec. https://mathiasbynens.be/notes/javascript-escapes#unicode-code-point IMO, this should be fixed as it only introduces complexity for validations. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
