There are various ways to enter accented characters, one of them is using html. For example, I can type Gâteaux by entering Gâteaux or Gâteaux; I can type entering François by entering François or François. Will search find posts using either of them if I search for Gateaux or Francois?

I should mention that this question was inspired by a recent discussion on MathOverflow: Formatting: Diacritics outside of Formulas (The same meta also has a closely related older discussion: LaTeX style accents in regular text.)

I have posted an answer in the sandbox to be able to test this here. (The answer contains only "html-versions" of Gâteaux, François, Gödel, Pólya, Čech.) They all seem to be working correctly with the exception of Čech.

Yes, it does work, but the highlighting on the found posts doesn't work. That was what initially got me confused.

It does search on the HTML encoded versions literally, so that is definitely not what you want.

As you see, the search for Francois yields the same post as François.

  • Yes, indeed. Doesn't seem to work for c vs. ç. Dec 29, 2016 at 14:55
  • It works as it does return the results, maybe it's just not perfect. Dec 29, 2016 at 14:57
  • I see that we both had the same idea to make some tests in the sandbox here and here.

  • @Sha does work indeed, just confusing highlighting. Dec 29, 2016 at 15:01
  • @ShadowWizard maybe it's not just perfect you mean that is a bug?

    @rene yeah, but only a cosmetic bug, not harming the search functionality. Dec 29, 2016 at 15:13
