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.
