I've noticed that SE can't deal with links nor tags which has a character with diacritic accent in it.

About links, I feel it's important to allow this as RAE website needs the accent and depending on the format, it doesn't work:

With tags it doesn't work at all:

So, the best thing would be using HTML encoding when writing the URL. However, this would make users search the encoding of the desired character, and users might not know how to do this. Thus, my opinion is that we should ask SO to implement that an with URL an accent that is not encoded works:

The user writes:


It shows:


In tags, it depends on how they are finally translated, but my opinion is that accents should work.

Do you feel this is important for the site, should make users to encode accents (or edit them), or should we ask to implement this feature (or fix the bug)?

  • You shouldn't often post "naked" URLs anyway. They're not user friendly. Better is something like RAE dictionary for "número". Commented Jun 8, 2012 at 9:15

    @hippietrail I always try to format as you, but that's not my point ;) The thing is using a diacritic without encoding doesn't work.

  • Yes that part is a valid bug. I think you should file it as a bug report on meta.SO - it may even already be there. Commented Jun 8, 2012 at 9:21

    This is part of our ongoing work to better support unicode characters on our sites in general. :)

The stripping issue in tags has been fixed for about a year. The URL portion of this issue isn't going to be worked because the changes required to the markdown implementation and tag sanitizer are substantial, and users can use the hyperlink button in the editing toolbar to safely render such URLs.

For a more complete explanation, please refer to balpha's answer here: https://meta.stackexchange.com/a/128824/136973


I'm not sure at what point this was fixed (for extended unicode characters in both urls and tags), but the example accented character links and tags all work/display fine as of 2019.
