It’s not that, but I have another clue.

This is the relevant line from fmtutil.cfg:

    pdftex pdftex language.def -translate-file=cp227.tcx *pdfetex.ini

Here’s output from building pdftex.fmt (from the build log of
texlive-latex-base):

Two things here:

“warning: Could not open char translation file `cp227.tcx'.” – Oh?  It’s
in the union, but maybe a search path in the configuration file is
misconfigured.

“dehyph-exptl: using an 8-bit TeX engine.” — hmm.  Probably correct,
because pdftex doesn’t natively support multibyte characters.  But maybe
a problem.

So the next step for me is to figure out how I can make pdftex find
cp227.tcx.
