12.3.5 Hexadecimal escapes
Hexadecimal escapes start with
\x and are then either followed by a
two digit hexadecimal number, or a hexadecimal number of arbitrary length
surrounded by curly braces. The hexadecimal number is the code point of
the character you want to express.
Note that a character that is expressed as a hexadecimal escape is considered as a character without special meaning by the regex engine, and will match "as is".
