- # We have to escape the escape characters because XRegExp compiles it first.

- # \p{L} = any letter in any language
- # \p{N} = any kind of numeric character
- # https://www.regular-expressions.info/unicode.html#prop is a good resource for
- # more obscure regex features. standard RegExp does not support these
