Comment:

 This isn't specific to superscript characters. The majority of printable
 non-ASCII characters will appear in a post's slug if it's entered into the
 post title.

 See `sanitize_title_with_dashes()` for where this behaviour is defined
 (and note that its description isn't very accurate when it comes to
 multibyte characters).

 Do superscript and subscript characters actually cause a problem when they
 appear in a post permalink?
