unicoderegexp
Various regular expressions for unicode character classes (letter, punctuation, number, etc.) and helper functions for composing them.
Used by the purify library.
The module exports a bunch of useful RegExps each with a single character class in them:
letter
mark
number
punctuation
symbol
separator
other
visible
printable
unicodeRegExp.visible.test("a"); // true
unicodeRegExp.visible.test(" "); // false
unicodeRegExp.visible.test("\u00a0"); // false -- a non-breaking space is not visible
To validate an entire string you need to build a new RegExp:
var visibleStringRegExp = new RegExp('^' + unicodeRegExp.visible.source + '*
