Bug ID: 234010
Summary: Lack of Unicode support in strfmon breaks monitary
formatting
Product: Base System
Version: 11.2-RELEASE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: misc
Assignee: b...@freebsd.org
Reporter: j...@herrskogen.se
This bug was manifested when using the PHP function money_format and
LC_MONETARY sv_SE.UTF-8 to format some currency. Instead of a space as the
thousand separator, it was a ?-symbol. I'm not very good at this, but this is
what I have come up with:
* FreeBSD is retrieving locale data from http://cldr.unicode.org
* In at least sv_SE.UTF-8, the value ending up as monitary thousand separator
is a unicode character (C2 A0).
* localeconv is fetching the data in /usr/share/locale/sv_SE.UTF-8/LC_MONETARY
and returning a pointer.
* __format_grouped_double (with the description "convert double to ASCII") is
calling localeconv to fetch the thousand separator and seems to only use the
first byte (C2).
* strfmon is calling __format_grouped_double to format the grouping of the
string and returns bad strings when using locales with unicode characters.
How to reproduce:
setlocale(LC_MONETARY, "sv_SE.UTF-8");
int i;
strfmon(buf, sizeof(buf), "%i", money);
printf("%s\n", buf);
for(i=0; i<sizeof(buf); i++) {
printf("%2d - %i \n", i, buf[i]);
}
