An important characteristic of a language's alphabet is that those who use
it know the order of its letters, and use it to consult telephone books,
indexes, etc. This is not true for a lanaguage's entire script--few users
of any roman script languages could say whether % (per cent) precedes or
follows * (asterisk). If this aspect of alphabets has already been
menitoned pleas excuse the redundancy. While the order of numerals (0-9)
is well known, whether they precede or follow A-Z is less clear to many
users of a language's script.
