How to create unicode slug for unicode title?

问题

I want to sanitize blog titles with unicode characters in url. I need to replace invalid characters and spaces with "-" for better seo rewriting like this.

Can anyone have any idea how to do it?

You can use this algorithm for an SEO-friendly Unicode URL:

1. Convert the text to Unicode Normalization Form C, i.e. precomposed characters.
2. Use a regular expression with Unicode character classes to replace each non-letter non-digit character with a space.
3. Remove leading, trailing and double spaces.
4. Shorten.
5. Replace spaces with hyphens.
