Site has a problem inserting links with spaces

Community Website and Forum

here's a link

but this is the URL:
https://github.com/STMicroelectronics/STMems_Machine_Learning_Core/tree/master/application_examples/lsm6dsox/Vibration%20monitoring

the site is replacing the space designator in the link, %20, with %2520.

FYI: %25 is the encoding of the percentage sign. %20 is the space character. %2520 is double encoding of the space.

It happens for other characters too.

In a link to: https://en.wikipedia.org/wiki/Nassi-Shneiderman_diagram
The dash gets replaced with %E2%80%93
and becomes: https://en.wikipedia.org/wiki/Nassi%E2%80%93Shneiderman_diagram.

Yet a link to this topic (which includes the same character) https://forum.arduino.cc/t/site-has-a-problem-inserting-links-with-spaces/1403788 is unaffected.

this has only become a problem recently

The bug has been reported to the Discourse developers here:

Unfortunately the reporter focused the report too much on the very specific conditions under which they encountered the bug, rather than identifying and describing the general nature of the bug. I'll add a higher quality report as a reply there.

URL links can’t have spaces in them.

A space is not a valid character in a URL according to the standards (RFC 3986).

If you try to paste a link with a space, most systems will either break it at the space or replace it with %20 (URL-encoded space).

Despite the title of the topic, the URL didn't contain a true space character. It instead contained %20.

The bug has now been fixed:

Thanks for your report @gcjr!
