@lyse@lyse.isobeef.org Sorry, I don’t think I ever had charset=utf8. I just noticed that a few days ago. OpenBSD’s httpd might not support including a parameter with the mime type, unfortunately. I’m going to look into it.
It should be fixed now. Just needed some unusual quoting in my httpd.conf: https://mail-archive.com/misc@openbsd.org/msg169795.html
