Error when using password containing question mark

[eldering]

On current main branch (and also on 8.2 branch) when I try to use a DB password containing a ?, then during the installation process I get this error:

make[1]: Entering directory '/home/jaap/domjudge/git/domjudge/webapp'
composer auto-scripts

and I see these errors in the symfony logs:

It seems that the password is stored and parsed from a URL and probably does not get URL encoded properly.

I wonder if this is the same as #2502.

Quite likely, yes.

I suspect the problem is in: webapp/config/load_db_secrets.php
