summary:
bpo-13802: Use non-Latin characters in IDLE's Font settings sample. (#3960)
Even if one selects a font that defines a limited subset of the unicode
Basic Multilingual Plane, tcl/tk will use other fonts that define a
character. The expanded example give users of non-Latin characters
a better idea of what they might see in the IDLE shell and editors.
To make room for the expanded sample, frames on the Font tab are
re-arranged. The Font/Tabs help explains a bit about the additions.
