Hi!
I'm currently seing strange behaviour with Text widgets in combination with
utf-8 and unicode strings:
For certain symbols, like 'ιΆ–', urwid craches when displaying them (stacktrace
below).
But if i encode this to utf08 before handing it to urwid.Text,
Its length gets calculated falsely:
>s=u'\u9896'.encode('utf-8')
> len(s) = 3
so I get two whitespaces after the symbol on my screen..
Best,
/p
