01 What is the TomTom Code?

In TomTom, the individual letters are represented by combinations of the characters / (slash) and \ (backslash).

abcdefghi
/////////// \//\//\/\\/\\\
jklmnopqr
\/\\/\\\/\//\////\///\//\\//\//
stuvwxyz
\/\\\/\\//\\/\\//\\\\//\/\//\/\

GC Wizard offers the possibility to replace these two characters with arbitrary others and thus display them e.g. TomTom Morse-like.
