A few pkg/DESCRs have ISO-8859-1 characters in them. These look funny in a UTF-8 terminal (one of two locales that OpenBSD supports, the other being the ASCII-only C locale). It might be best to restrict them to plain ASCII.
I would send a patch, but it would probably get weirded out by my mail client.
