Package: libc6
Version: 2.36-6
Severity: minor
I've been trying to work out why the Chinese translation for free
doesn't want to line up the columns like everyone else, report is
at [1]
For some reason, it thinks the strange colon used in the translation is
one character wide, but its actually two. This means the column is
mis-aligned.
A small test program:
------
#define _XOPEN_SOURCE 1
#include <stdio.h>
#include <stdlib.h>
#include <wchar.h>
void printme(char *str)
{
int len, width;
wchar_t wstr[BUFSIZ];
len = mbstowcs(wstr, str, BUFSIZ);
width = wcswidth(wstr, 99);
printf("len=%d width=%d\n",
len, width, str);
printf("%s%.s%s\n", str, 6 - width, "blah");
}
int main()
{
printme(":");
printme("：");
}
------
$~/width
len=1 width=1
:blah
len=-1 width=1
：blah
We can see that the second colon is 2 wide, the "b" in blah lines up
with the "n" in len but wcswidth thinks it is 2. I have no idea why
this is so and even where this information comes from.
It's not the end-of-the world sort of bug, but it is a very stange one.
