When trying out the box demo, instead of a border, it only shows question marks. I'm using st, and I tried it with and without the boxdraw patch. It doesn't effect functionality, but if there's a way to fix it that anyone knows of, [that'd] be cool.

@rivo yes, exporting that before the program is run, or putting it in my .profile worked. Should i close this issue?

I'm not sure what's going on but I've tried the sample project on mac and linux with iterm2, apple terminal, and on linux xfce_terminal and I always get question marks. I've tried several different profiles and fonts.

I'm new to golang, so if this is a rookie mistake, apologize in advance for wasting your time.

any help is appreciated!
