I bumped into this commit log message and thought it might amuse you.

    [preconv]: Improve skipping logic in test.

    * Exit with failure status before test for skip condition.
    * When skipping, report why.
    * Conditionalize fallback character set.  Use the availablity of
      locale(1) as an indicator, but not what it reports for the "C"
      locale's character set because preconv overrides ANSI_X3.4-1968 with
      ISO-8859-1.  On some systems the "C" locale uses UTF-8.   I feel
      certain this heuristic will let me down sooner or later.

...and sure enough it has.  :)

Any luck re-running the command with the corrected environment variable
name?

$ /usr/bin/env LC_ALL=C printf 'Eat at the caf\351.\n' | /usr/bin/od -x
