java slugify string for non English characters

Question

I need to create slug strings(Human-readable URL slugs from any string) for English and non English characters.. for example Chinese, Japanese, Cyrillic and any other.

So, each string(for all languages) must be translated in English characters a-z, 0-9, for example java-slugify-string-for-non-english-characters

How can I achieve this in Java ?

So, for "ログイン" which I got from the google.co.jp home page, what would you expect it to "slugify" to? — Kenster, Mar 15 '15 at 21:30

You can use Slugify which is written in Java: https://github.com/slugify/slugify

I am not sure. The Slugify constructor accepts a Locale object so it may do. – Dermot Blair Mar 15 '15 at 21:04
I checked the code, the slugify library removes all non-ascii characters. – Ayman Aug 09 '15 at 12:37

Convert each character into its integer representation, and concatenate:

    String foo = "中国";
    StringBuilder result = new StringBuilder();
    for (int i=0; i<foo.length(); i++) {
        result.append("\\").append((int)foo.charAt(i));
    }
    System.out.println(result);

Produces:

"\20013\22269"

...which is pretty easy to split and convert back to a string. You can also pad the numbers, convert them to hex, and add exclusions so that ASCII/English characters aren't converted, if you'd like. You could also have a look at other, more stardard ways of doing this sort of encoding.
