Good daytime!
At least in utility/shared.c:wordwrap_string() strlen() is used to
determine number of characters in the string. This gives wrong result
on multibytes encoding.
There are several code bases for this situation.
>From (patched) Midnight Commander code:
=====
size_t mbstrlen (const char *str)
{
if (SLsmg_Is_Unicode) {
size_t width = 0;
for (; *str; str++) {
wchar_t c;
size_t len;
len = mbrtowc (&c, str, MB_CUR_MAX, NULL);
if (len == (size_t)(-1) || len == (size_t)(-2)) break;
if (len > 0) {
int wcsize = wcwidth(c);
width += wcsize > 0 ? wcsize : 0;
str += len-1;
}
}
return width;
} else
return strlen (str);
}
=====
Also there is code available at
http://www.koders.com/c/fid4F30C99A88AEA6396B65ADED79AB7664C69E3500.aspx
and neighbours.
Q: Do we want to do something with current behavior? I consider it as
a bug, but maybe someone has another opinion.
