369 Unlike in XEmacs v19 and FSF Emacs, a character is its own primitive type.
|
|
70
|
370 Any character can be converted into an equivalent integer using
|
|
280
|
371 `char-int'. To convert the other way, use `int-char'; however,
|
|
70
|
372 only some integers can be converted into characters. Such an integer
|
|
110
|
373 is called a `char-int'; see `char-int-p'.
|
|
70
|
374
|
|
|
375 Some functions that work on integers (e.g. the comparison functions
|
|
|
376 <, <=, =, /=, etc. and the arithmetic functions +, -, *, etc.)
|
|
|
377 accept characters and implicitly convert them into integers. In
|
|
|
378 general, functions that work on characters also accept char-ints and
|
|
|
379 implicitly convert them into characters. WARNING: Neither of these
|
|
|
380 behaviors is very desirable, and they are maintained for backward
|
|
|
381 compatibility with old E-Lisp programs that confounded characters and
|
|
|
382 integers willy-nilly. These behaviors may change in the future; therefore,
|
|
|
383 do not rely on them. Instead, use the character-specific functions such
|
|
|
384 as `char='.
