From 844212d94f582c4e3c5055e0a1524931e89ebe76 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Wed, 9 Sep 2015 05:13:33 +0000 Subject: make nl_langinfo(CODESET) always return "UTF-8" this restores the original behavior prior to the addition of the byte-based C locale and fixes what is effectively a regression in musl's property of always providing working UTF-8 support. commit 1507ebf837334e9e07cfab1ca1c2e88449069a80 introduced the codeset name "UTF-8-CODE-UNITS" for the byte-based C locale to represent that the semantic content is UTF-8 but that it is being processed as code units (bytes) rather than whole multibyte characters. however, many programs assume that the codeset name is usable with iconv and/or comes from a set of standard/widely-used names known to the application. such programs are likely to produce warnings or errors, run with reduced functionality, or mangle character data when run explicitly in the C locale. the standard places basically no requirements for the string returned by nl_langinfo(CODESET) and how it interacts with other interfaces, so returning "UTF-8" is permissible. moreover, it seems like the right thing to do, since the identity of the character encoding as "UTF-8" is independent of whether it is being processed as bytes of characters by the standard library functions. --- src/locale/langinfo.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'src') diff --git a/src/locale/langinfo.c b/src/locale/langinfo.c index 776b4478..69693fff 100644 --- a/src/locale/langinfo.c +++ b/src/locale/langinfo.c @@ -33,8 +33,7 @@ char *__nl_langinfo_l(nl_item item, locale_t loc) int idx = item & 65535; const char *str; - if (item == CODESET) - return MB_CUR_MAX==1 ?
