Attempting to invoke wget with the --convert-links / -k parameter works as
intended, but fails to account for the fact that CSS url() parameters cannot
contain spaces.
In my case, wget invoked on Apr 20, 2023 with
wget -rk -l 1 https://www.calpoly.edu/
converted the filename
20200115-Sailplane-JoeJ0583-min%20%281%29.jpg
to
20200115-Sailplane-JoeJ0583-min (1).jpg
.
The page uses the CSS
background-image:
url(/sites/calpoly.edu/files/styles/width_2048px/public/2020-01/20200115-Sailplane-JoeJ0583-min%20%281%29.jpg?itok=QrMTAlEd)
on a div, which breaks when containing a space.
This bug has likely always been in wget. Here is a Stack Overflow question
detailing the bug from 10 years ago:

There is no relevant wget output for this bug.
