There are no issues with non-Latin1 text. set_width_chars() uses the
'average char width' from the Pango font, which is somewhat a voodoo
number, but does consider the existence of non-Latin1. After all
that's the point of Pango.

set_width_chars() is intended for when you don't know exactly which
chars it will contain - if you know the entry will contain "lllllll"
then setting the usize is probably right, but also, using a label
rather than an entry is probably right. ;-)
