&nbsp character in title generates a permalink (and slug) with space

[ace2_heart]

If a title has an &nbsp character copy pasted or if the permalink has a &nbsp copy pasted
It will generate a permalink and slug with an space breaking some elements on the site

I generated an empty wordpress install without any plugins to test it, and it has the same problem

Works for me

Hi @ace2_heart thanks for the ticket and welcome to WordPress Trac,

I can't reproduce the issue on a fresh install (see screen capture above). I tested it in the permalink edition and in the title field and both are correctly escaping the non-breaking space. Can you provide us some further information to reproduce the bug please?

Cheers,

Hi @ace2_heart, thanks for the ticket!

  is supposed to be converted to a hyphen by sanitize_title_with_dashes()​.

Are you sure the issue still happens on a clean install with all plugins disabled and a default theme (Twenty Seventeen) activated?

Hi, I created an empty install here, you can access it

The parmalink are as following:

I just saw the demo you posted, instead of using the   text on the title, tried to copy/paste the actual space character.

Ok thanks for your answer.

So the issue happens with control marks like %e2%80%. Indeed, I'm able to reproduce this specific issue.

By the way, you are running WP 4.8.7 which is quite an old version. But the issue also happens in 4.9.8.

Thanks,

I'd say it's more like an edge case, but yep, thank you for your ticket :)

I'm hoping to submit a patch for this ticket in the next couple of days, I have seen it pop up in other places with other characters with a clear case for being sanitized out of URIs, such as the unicode line separator.
