OpenBSD's default behaviour is still tuned towards ASCII-only.
When using UTF-8 you should also configure a font which can display
the fancy glyphs. The Dejavu font should work: In ~/.Xdefaults:
  XTerm*Font: -Misc-Fixed-Medium-R-Normal--18-120-100-100-C-90-ISO10646-1
At least it was working for me 12 years ago:

Nowadays I use gnome/xfce where fonts are nice out of the box.
