    [grotty]: Skip part of test if no UTF-8 support.
    
    * src/devices/grotty/tests/basic_latin_glyphs_map_correctly.sh: Skip
      test of 'utf8' output device if locale lacks UTF-8 support.  But if
      the 'ascii' or 'latin1' test cases have already failed, report that
      instead.
    
    Fixes <https://savannah.gnu.org/bugs/?61891>.  Thanks to Bjarni
    Ingi Gislason for the report.
