Solved. Summary: I started tmux in my ~/.profile before setting LANG and LC_ALL. Changing to starting tmux from $ENV, after setting & exporting LANG and LC_ALL solved the display issue with accented characters.
This, however made the panel layout go really wonky (bad line-drawing characters). I use iTerm on a Mac to connect to my OpenBSD machine, and in iTerm there's a "Treat ambigous-width characters as double width" setting. Unsetting this solves the panel layout problem. Thanks to Nick for pointing me in the right directions. I don't know if any of this helps Jan (the original poster) though...
