URL with "special" characters, like `ë`

Bug Report

We're experiencing some un-expected behaviour, that i can reproduce on a fresh Craft & Blitz install. Make sure server rewrites are active.

• Create a section, only title field is enough, and create a twig view for it, so we can serve it
• Create an entry with title tëst, so the slug will also have the ë
• View in browser, and the cache (db & file) will be generated as expected

CraftCP, Blitz diagnostics, Tracked Pages:

Generated cache file:

Then in the browser, change the url and request the page without te ë, so like: /test. The following happens:

• CraftCP, Blitz diagnostics, Tracked Page "tëst", is overwritten by slug test
• The new page-cache is generated

So the situation is as follows:

CraftCP, Blitz diagnostics, Tracked Pages:

Changed from tëst to test
Generated cache file:

Both pages are here

When we now change the contents of the entry, Blitz will only update the current Tracked Page test, and leave the generated other cache file as is. So when we request the entry with the original url /tëst, it will serve the generated old cache via the server rewrite, and it's never refreshed.

Is there a setting we're missing, or is this an (un)known issue?

Hope you can help me. Thanks in advance!

Best regards,
Jan
