# A note about SAFE_REGEX:
|
|
# We have to escape the escape characters because XRegExp compiles it first.
|
|
# So it's equivalent to `^[\p{L}\p{N}\s\-_!&\(\)]+$]
|
|
# \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
