commit 20de8cba8f83342809a5ef94802cf7de8550ce69
Author: Alexandre Detiste <alexandre.detiste at gmail.com>
Date:   Wed May 6 14:23:13 2015 +0200

    degrade non-ascii characters when running with LANG=C
    
    the characters needed for "Dračí Historie" have
    been added too
    
    on a matrix printer, you can overwrite a character,
    so much fun:
    
    € = 'C' + backspace + '='
