In C++, it's possible create a UTF-8 string using this kind of notation: "\uD840\uDC50"
.
However this doesn't work in PHP. Is there a similar notation?
If not, is there any built-in way to create a UTF-8 string knowing its Unicode code point?
I've ended up implementing it like this:
$utf8 = html_entity_decode("一", ENT_COMPAT, 'UTF-8');
