A slug is a SEO-friendly, human-readable version of a URL. Generally used on most blog software for permalinks via a blog’s title (exactly like my blog here), or basically any string you want to turn into a friendly URL. Sure you could just use PHP’s urlencode (or other language equivalent) but then you’re stuck with unfriendly characters translated into hex codes: %2F%20
The problem is greater when the content you want to Slug is UTF-8 encoded and contains non-ASCII characters. How do you slug a word like: Iñtërnâtiônàlizætiøn?
