From 6e3fe92b20edb1d91683efa9aea68d35a887a83c Mon Sep 17 00:00:00 2001 From: Jean Abou Samra Date: Thu, 8 Dec 2022 13:02:19 +0100 Subject: Ignore LC_CTYPE if set to "UTF-8" LC_CTYPE is set to "UTF-8" on some macOS systems, which is POSIX-compliant in a strict sense, but breaks the usual assumption that a locale name has the form "ll_LL.encoding". https://unix.stackexchange.com/questions/503110/valid-values-for-lc-ctype Previously, this would cause the warning Fontconfig warning: ignoring UTF-8: not a valid region tag Now, we just skip this variable if set to "UTF-8", since that value doesn't give any language information, and move on to try LANG. --- src/fcdefault.c | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) diff --git a/src/fcdefault.c b/src/fcdefault.c index 6995216..d00c494 100644 --- a/src/fcdefault.c +++ b/src/fcdefault.c @@ -62,7 +62,17 @@ retry: if (!langs || !langs[0]) langs = getenv ("LC_ALL"); if (!langs || !langs[0]) - langs = getenv ("LC_CTYPE"); + { + langs = getenv ("LC_CTYPE"); + // On some macOS systems, LC_CTYPE is set to "UTF-8", which doesn't + // give any languge information.
