Update of bug #67244 (group groff):
Status: In Progress => Need Info

Follow-up Comment #7:
After I made the changes in comment #6, I observe that the following document
falls flat on its face when producing PostScript with my working copy.
This is a regression from released _groff_, though arguably a "correct" one.

For those inexperienced at reading "grout", that's a longish way of producing
a blank document.
Turning the "char" warning category back on reveals why.

Should we add `fchar` fallbacks to "fallbacks.tmac" to mop up the basic Greek
alphabet?
Should we add _further_ `char` fallbacks to sponge up even precomposed forms
of Greek letters with diacritics, degrading them to their base characters?
Even the latter won't get us full coverage of the Unicode Greek block.
PostScript fonts did not standardize glyphs for digamma and other archaic
letters.
