regex - How to match a Unicode letter with a JSON Schema pattern (regular expression) -

i need good/easy way of matching valid unicode letter within json schema pattern using regular look [a-za-z] not plenty in order back upwards letters different countries, e.g. china , greece. know possible e.g. perl , xregexp using \p{l} or \p{letter} (source: http://www.regular-expressions.info/unicode.html).

how express \p{l} in json schema pattern? preferably way don't have explicitly list possible valid unicode letters.

thanks in advance! :-)

json schema uses same syntax regular expressions ecmascript/javascript. such regular expressions can generated combining regenerate unicode data. here’s illustration node.js script generates regular look equivalent \p{l}, i.e. matching symbols in l unicode category:

// run `npm install regenerate unicode-7.0.0` before running script. var regenerate = require('regenerate'); var l = require('unicode-7.0.0/categories/l/code-points'); // or `symbols` — doesn’t matter var set = regenerate(l); console.log(set.tostring());

now, let’s run script:
