I can see that the problem is that the charset is shifted to the
graphic set. After using git bisect I can see that the offend
commit is 7a4eefe, that basically add support for G0 and G1.
After running wicd-curses, I can see that it print ^[)0, that means
shift G0 to the graphic charset, so I think st is making the correct
here. Another point is the terminfo definition. I can see that we have
enacs and smacs with '\E(0', so I am not sure what sequence wants to
send wicd-curses, and in fact I don't know exactly the difference between
them:
- enacs: enable alternate char set
- smacs: start alternate char set
I will take a look to my terminfo book later at home, but I think this is
a problem related to the implementation of urwid.
