Description
It looks like the hyphenation patterns are being loaded with active chars active (and set to \relax), rather than \catcodeed to letters.
The font I was trying lacks an e-grave:
! Improper \hyphenation will be flushed.
ѐ->\relax
\@ctivede@
l.183 fѐ
-ri
No pages of output.
Looking at the hyphenantion-including fragment and ptx2pdf.tex, \liter@lspecials`, called before the hyphen patterns are loaded, makes some some well-defined space chars, hyphens, NBSP, etc. return their natural values, but doesn't touch anything made active by the fallback font mechanism.
