Trouble defining new filtering rules with diacritics

[hieutkt]

Perfect! char-fold-to-regexp solves some of the other edge-cases that I'm thinking about, too!

Thanks a lot. I'm closing this issue.

You may be thinking backwards about how to do this. A matching style gets called on the pattern you type to turn it into a regexp. So here's what happens with the remove-diacritics matching style: say you have "résumé" among the candidates and you type "resume" at the prompt, then remove-diacritics gets called with the pattern you typed, namely "resume", and turns it into the regexp "resume" which, of course, does not match "résumé".

What you need instead of remove-diacritics is a function that turns "resume" into some regexp that does match "résumé". The built-in function char-fold-to-regexp fits the bill, so you can delete your remove-diacritics and add char-fold-to-regexp directly to orderless-matching-styles.
