PHP 7: Unicode escape syntax doesn't work on s

Question

Whenever strings are set with single quotes the unicode doesn't get decoded but the unicode does get decoded when set with double quotes.

How do I get the strings set by single quotes also to be decoded?

PHP

$poo = '\u{1F6BB}';
echo $poo;
$poo = "\u{1F6BB}";
echo $poo;

OUTPUT

\u{1F6BB}

The point of single-quoted strings is that they don't support escape characters.

The documentation says this very clearly:

All other instances of backslash will be treated as a literal backslash: this means that the other escape sequences you might be used to, such as \r or \n, will be output literally as specified rather than having any special meaning.
