In TomTom, the individual letters are represented by combinations of the characters / (slash) and \ (backslash).
a | b | c | d | e | f | g | h | i |
/ | // | /// | //// | / \ | //\ | //\ | /\\ | /\\\ |
j | k | l | m | n | o | p | q | r |
\/ | \\/ | \\\/ | \// | \/// | /\/ | //\/ | /\\/ | /\// |
s | t | u | v | w | x | y | z | |
\/\ | \\/\ | \//\ | \/\\ | //\\ | \\// | \/\/ | /\/\ |
GC Wizard offers the possibility to replace these two characters with arbitrary others and thus display them e.g. TomTom Morse-like.
