Thanks Daniel (and Ivan as well, off-list), that worked a treat ! :-)

Only drawback I found, is that I must now have TWO #defines for each and
every custom character: one #define to represent the character as a
string, so I can embed it into a string, and also all the #defines I
already had, which represent the actual numerical value, for when I
need to print an individual/discrete character rather than print a
string. It's not the end of the world, but not very elegant either, so
if anybody has a solution to make do with only one define per character,
I am all ears ;-)
