string.normalize() doesn't seem to work

[ryanxcharles]

I was eager to replace my dependency on unorm, which does the equivalent of ES6's unicode .normalize(), but as best I can tell, .normalize() doesn't work. It returns the same string, unchanged, un-normalized. I have run tests with a list of Japanese words. I am using io.js 2.0.1. The following example script should pass, but it fails (be sure to "npm install unorm" before running it):

"use strict";
let assert = require('assert');
let unorm = require('unorm');

The same script fails if normalization NFD is used instead of NFKD. It passes for NFC and NFKC, but that may be because these strings simply aren't supposed to be changed for those normalizations. The output of the above script is:

es6changed: 0

*edit, corrected variable names

[Fishrock123]

Right, .normalize() doesn't work unless you have Intl. We currently don't build with it by default, see: #238

You can build yourself and bundle it with the instructions in the readme.

[ryanxcharles]

Thanks! Perhaps this function should throw an error if Intl was not compiled in? By silently failing, some people will run this function thinking it works and therefore introducing bugs into their software.

[Fishrock123]

I think that's probably a good idea. It's on v8's side though. Cc @domenic?

[domenic]

V8 doesn't really support builds without Intl, so I doubt they are going to bother to change how this works.

[ryanxcharles]

If building without Intl means having an incorrect conformance to ES6, then perhaps Intl should be built in by default?
