Support UTF-8 in the input bar
* introduce RP_IS_UTF8_{CHAR,CONT,START} macros. Those yield non-zero
only if the locale is UTF-8.
* use those macros in editor.c to properly handle UTF-8 multibyte
characters.
* use them also in input.c:update_input_window, to draw the cursor
Reviewing and comments are welcome.
Patches for generic support of multibyte encodings are welcome too.
UTF-8 was chosen because of its processing simplicity and its wide use,
not because of any political opinion or religious belief. ;)
