AutoCAD stores a TrueType text style's family (e.g. "GOST type A") in the style's ACAD xdata
and leaves the font file name empty. Styles without a file now take that family.
Family-name lookups also look in files whose name starts with the family's first word, so
"GOST type A" finds GOST.TTF (the stem shares only 4 characters with the family name).
