The stand-ins for the standard fonts (PDFium's Foxit fonts) have neither the
comma-below letters nor a commaaccent glyph, and the composite-letter patch
left comma accents out. A non-embedded font naming /scommaaccent therefore
drew nothing, which is the blank "si" left in Romanian XFA forms, and
/tcommaaccent drew a cedilla through the glyph list's alias to U+0163.
Romanian s/S/t/T and Latvian k/K/l/L/n/N/r/R/G with a comma below are now
built from the letter and the font's comma, scaled to three quarters and set
just under the baseline, moved back along the slant in italics. The uni021A and
uni021B names of T and t with a comma below, which the glyph list
does not name, resolve by code point. Lowercase g with its turned comma above
is still not built.
