Summary: raw_input problem with readline and UTF8
Initial Comment:
Backspace doesn't remove all bytes of a multi-byte
UTF-8 character.
To reproduce the problem:
$ export LANG=en_US.UTF-8
$ python
Python 2.3.4 (#1, Jun 11 2004, 16:35:29)
[GCC 3.3.3 20040412 (Gentoo Linux 3.3.3-r3, ssp-3.3-7,
pie-8.5.3)] on linux2

>>> import readline
>>> raw_input() # ä, return
ä
'\xc3\xa4'
>>> raw_input() # ä, backspace, return
'\xc3'
>>>
A small C program does not have the same problem:
#include <stdlib.h>
#include <stdio.h>
#include <readline/readline.h>
#include <readline/history.h>
void pprint(const char *s);
int main(void) {
char *line;
for (;;) {
line = readline("> ");
if (!line)
break;
pprint(line);
free(line);
}
return 0;
}
void pprint(const char *s) {
while (*s) {
if (isprint(*s))
putchar(*s);
else
printf("\x%x", *s & 0xff);
s++;
}
putchar('\n');
}
