It depends on what kind of comparison one wants. Simplest is to use '='. To ignore case and treat bytes 128-255 as Latin-1 characters, use 'downcase' first. To ignore case and treat bytes 128-255 as uninterpreted bit patterns, use 'unibyte-char-to-multibyte' before downcasing. Etc. > we don't have a way of distinguishing between characters and > bytes, unless we look on something besides the arguments themselves. Yes, that's right.
