I nearly said as much in my previous post but I thought it was too obvious to mention. Just about everything about Unicode characters -- from how the Unicode Standard refers to them to how most computer languages represent them -- is in terms of hexadecimal code values. In my experience, even if the encoding isn't Unicode, most specifications of character sets and most ways of working with code values use hexadecimal character numbers. The only application that I can think of that absolutely requires decimal code values instead of hexadecimal is the SGML Declaration (and I don't think that you're going to surprise us with the SGML Declaration for SML anytime soon). Working with hexadecimal code values some of the time and decimal code values some of the time is a real pain. When the character set's documentation uses hexadecimal code values, it's much easier if you can enter hexadecimal code values in your data.
