Espressione regolare Javascript per la punteggiatura (internazionale)?

Question

Ho bisogno di un'espressione regolare da abbinare a tutti i segni di punteggiatura, come lo standard [,! @ # $%^& *()], ma include marchi internazionali come il punto interrogativo spagnolo capovolto, periodi cinesi, ecc. Il mio google-fu si sta avvicinando. Qualcuno ha una tale espressione regolare a portata di mano che è compatibile con Javascript?

Answer 1

Se è possibile utilizzare un plug-in, è disponibile un plug-in per JavaScript: XRegExp Unicode plugins. Questo aggiunge il supporto per le categorie, gli script e i blocchi Unicode (personalmente ho letto solo su di esso, non l'ho mai usato).

Con questo plug-in dovrebbe essere possibile utilizzare categorie Unicode come \p{P} come spiegato allo regular-expressions.info.

Aggiornamento: OK, l'ho provato e sembra funzionare correttamente.

È necessario ottenere la libreria da XRegExp e in aggiunta i plug-in Unicode Base e Unicode Category (collegati in alto).

<script src="xregexp.js"></script> 
<script src="addons/unicode-base.js"></script> 
<script src="addons/unicode-categories.js"></script> 
<script> 
    var unicodePunctuation = XRegExp("^\\p{P}+$"); 

    alert(unicodePunctuation.test("?.,;!¡¿。、·")); // true 
</script> 

Gli avvisi di cui sopra true. Ho incluso una punteggiatura spagnola e cinese nella mia stringa di prova, "?.,;!¡¿。、·".

Answer 2

Beh ... idk quanto esteso sarebbe, ma è possibile utilizzare questo:

[^\w\s\n\t] 

Answer 3

tuo regex sarebbe simile ...

/[,!@#$%^&*()\u9999]/ 

Dove si sostituisce ogni \u9999 con il codice Unicode per gli altri caratteri di punteggiatura.

Se si potesse trovare un gruppo in una gamma, si potrebbe specificare che con l'operando - gamma, per esempio \u9990-\u9999.

Per quanto ne so non è possibile utilizzare qualcosa come \pP in regex JavaScript.

Aggiunta alla risposta di @ stema (https://stackoverflow.com/a/7578937/114140) ... ecco la regex come stringa (quindi non è necessario ingrandire il progetto con XRegExp).

Per Python questo regex da rimuovere dal inizio e la fine di qualsiasi tipo di segni di punteggiatura:

import re 
def cleanspecialcharacters(str): 
    regex = re.compile((
