# Mapping from LC_CTYPE locale to MIME's charset values
# Format is:
#	LC_CTYPE	charset
#
# That format can be used override mapping given by nl_langinfo(CODESET)

# If LC_CTYPE is on form
#	LL_cc.encoding
# then also following formats are available:
#	LL_cc		charset
#	LL		charset
#	*.encoding	charset
# These mappings are only used if nl_langinfo(CODESET) is not supported
