It is commonly used in Unicode, which is of interest to members of this
message-group. I think its usefulness there consists in permitting
four-digit addresses for each cell in the Unicode table of characters.
Macintosh computers come with a "keyboard" named "Unicode Hex Input,"
which enables inserting characters by their hexadecimal address. I have
noticed that many information sources nowadays give both hexadecimal
addresses as well as decimal addresses for a character. Hexadecimal is
more elegant and arguably easier to remember.
