    tmac/ps.tmac: Fix Savannah #62955.
    
    * tmac/ps.tmac: Fallback definitions for glyphs that usually come from
      special fonts should use `schar` instead of `fchar`.  [Define fallback
      special characters using `schar` instead of `fchar` for glyphs that we
      do not expect to find in text fonts; that is, they don't have bold,
      italic, and bold-italic stylistic variants.  This means all special
      character definitions in the file except for rules, ligatures, and
      digraphs.  Problem dates back to a series of commits from March 2002
      to February 2003, straddling the introduction of the `schar` request
      in November 2002. --GBR]
    
    Fixes <https://savannah.gnu.org/bugs/?62955>.
