3.3.3 Specifying character codes

Most of the programs allow you to specify character codes for various purposes. Character codes are always parsed in the same way (using the routines in `lib/charcode.c' and `lib/charspec.c').

You can specify the character code directly, as a numeric value, or indirectly, as a character name to be looked up in an encoding vector.

3.3.3.1 Named character codes		Character names are looked up in the encoding.
3.3.3.2 Numeric character codes		Decimal, octal, hex, or ASCII.
