Regex to capture Vietnamese characters (aăâbcdđ..., àáảãạ).

/^[a-z\u0111\u0300\u0301\u0302\u0303\u0306\u0309\u031b\u0323]+$/i

Usage:

regexp.test(str.normalize('NFD'))

Vietnamese characters actually not having 'fjwz', I'm just lazy so I use a-z instead.

What are '\uxxxx' characters anyway? Well, good question.

They are diacritics marks, as extract from, e.g. 'ắ'.normalize('NFD').
