Hello Luke-Jr,

please keep the discussion on the list.

I had written:
Simply use the digits “0” through “9”, and the
letters “A” through “F”;

You have written:
This makes it more complex to differentiate between numbers and
letters/units/etc.

In any case, you have to know the base of every number
you are going to parse. This stems from the fact that
the same digits are used for all number systems. Note
that Unicode is a character-encoding standard, hence
cannot do anything about this sort of ambiguity.

Best wishes,
  Otto Stolz
