Really show correct G0 and G2 character set in widgets

Browse Source 
Amendment to 7b59c78. This should prevent spurious NOS character sets from
appearing in the widgets, and should also prevent the G0 and G2 character
sets from getting mixed up in the widgets when those triplets are within
object definitions.

The G0 and G2 character set in the widgets may still be incorrect in corner
cases of objects invoked within areas of the page where the character set
has been changed either with the ESC/Switch spacing attribute or with the
"modified G0/G2 character set designation" triplet.
