This function returns true if git is running under an UTF-8 locale. pcre in the next patch will need this. is_encoding_utf8() is used instead of strcmp() to catch both "utf-8" and "utf8" suffixes. When built with no gettext support, we peek in several env variables to detect UTF-8. pcre library might support utf-8 even if libc is built without locale support.. The peeking code is a copy from compat/regex/regcomp.c Helped-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
