javascript - Convert non-ASCII characters (umlauts, accents...) to their closest ASCII equivalent (slug creation)

Question

I am looking for way in JavaScript to convert non-ASCII characters in a string to their closest equivalent, similarly to what the PHP iconv function does. For instance if the input string is R?nades p? Skyttis i ?-vik, it should be converted to Ranades pa skyttis i o-vik. I had a look at phpjs but iconv isn't included.

Is it possible to perform such conversion in JavaScript, if so how?

Answer 1

The easiest way I've found:

var str = "R?nades p? Skyttis i ?-vik";
var combining = /[u0300-u036F]/g; 

console.log(str.normalize('NFKD').replace(combining, ''));
