Javascript regular expression for punctuation (international)?

Question

I need a regular expression to match against all punctuation marks, such as the standard [,!@#$%^&*()], but including international marks like the upside-down Spanish qu

From ES 2018, Unicode property escapes are supported. You can use \p{Punctuation} or just \p{P} (the same as the XRegExp answer) to match any punctuation character (by the Unicode definition), or \P{Punctuation} to match any non-punctuation character.

If you want to match any "non-word" character, like a Unicode version of \W, you can try something like:

[^\p{Alphabetic}\p{Mark}\p{Decimal_Number}\p{Connector_Punctuation}\p{Join_Control}]

(as recommended in the proposal for the feature). You might want to remove \p{Connector_Punctuation}, since that includes underscores and similar.

Don't forget to add the u flag to your regular expression to make it Unicode-aware and enable this feature.
