Birb can't add feed if it has invalid XML characters

[bannmann]

Requested feed: https://www.captain-futura.de/feed/

Birb responds:

Hm, I can't find a feed for this site.

Taking the "for this site" part verbatim, I also tried to enter the site URL https://www.captain-futura.de/ instead of its feed URL, but got the same result.

It appears the feed contains an invalid character. Go's built-in XML parser is pretty finicky about this, so it complains with this error: XML syntax error on line 535: illegal character code U+0003

I've seen this in about 3% of the 10k+ feeds from the Kagi Small Web that I imported before the release. I'll get back to this later and look for a way to sanitize the input if it has this kind of easy-to-fix problems.

I suspect this is also messing with youtube's atom feeds at the moment.

For example, this youtube feed was set up a while ago and apparently works fine

however new youtube feeds get the

Hm, I can't find a feed for this site.

Also confirming that it's affecting Youtube feeds

Youtube problem is unrelated, opening a different issue for it.

This feed also isn't accepted: https://fd.nl/?rss
Would be nice if it would eturn that a feed /is/ found but that it can't be processed
