Right you are. This varialbe shows "utf-8." And, as Pascal notes,
everything above char 127 is out of ASCII range. If I remember right, back

included some Western European vowels with diacritics and box drawing
characters.

I usally use arialuni.ttf which has fairly good coverage of the Basic
Multi-lingual Plane (used with 21.3 w32 build).
