Wrong length returned for some Emojis

[sallar]

Hi there,

I noticed that the library is returning the wrong length for some emojis:

utils.length("❤️"); // Returns 2
utils.length("💪🏼"); // Returns 2 because it has a "color" overlay (compared to 💪 which is 1)
utils.substring("👦🏻", 0, 1); // Returns 👦!

I wish I could fix it myself, but I’m a bit of noob when it comes to unicode strings...
Thanks.

I honestly have no idea either...
I just packaged up the code available in this blog post so I could use it across my projects.

My intention was to use it to get-by until I could use ES6.
I'll see what I can do, but it might be time to move to a better solution (sorry!)

Hey there,
I used this monster regex in my own package last night... borrowed from lodash which is the only package which gets it right:
