Does emacs have an incremental search mode, where searching for a character will search for itself and for any other versions of the character with accent marks, similar to how Google Chrome (at least v27) will do when searching in a page?

Alternatively, is there an additional library or piece of elisp code that can put incremental search in such a mode?

For example, incremental search for:

• 'manana', would find 'manana' or 'mañana'
• 'motley crue', would also find 'Mötley Crüe' (with case-sensitivity off).

Even a solution that only covers a subset of these characters would be helpful.
