SummaryEncode-Locale - Determine the locale encoding
DescriptionIn many applications it's wise to let Perl use Unicode for the strings it processes. Most of the interfaces Perl has to the outside world is still byte based. Programs therefore needs to decode byte strings that enter the program from the outside and encode them again on the way out. The POSIX locale system is used to specify both the language conventions requested by the user and the preferred character set to consume and output. The "Encode::Locale" module looks up the charset and encoding (called a CODESET in the locale jargon) and arrange for the Encode module to know this encoding under the name "locale". It means bytes obtained from the environment can be converted to Unicode strings by calling "Encode::encode(locale => $bytes)" and converted back again with "Encode::decode(locale => $string)". Where file systems interfaces pass file names in and out of the program we also need care. The trend is for operating systems to use a fixed file encoding that don't actually depend on the locale; and this module determines the most appropriate encoding for file names. The Encode module will know this encoding under the name "locale_fs". For traditional Unix systems this will be an alias to the same encoding as "locale". For programs running in a terminal window (called a "Console" on some systems) the "locale" encoding is usually a good choice for what to expect as input and output. Some systems allows us to query the encoding set for the terminal and "Encode::Locale" will do that if available and make these encodings known under the "Encode" aliases "console_in" and "console_out". For systems where we can't determine the terminal encoding these will be aliased as the same encoding as "locale". The advice is to use "console_in" for input known to come from the terminal and "console_out" for output known to go from the terminal. In addition to arranging for various Encode aliases the following functions and variables are provided: =over =item decode_argv( ) =item decode_argv( Encode::FB_CROAK ) This will decode the command line arguments to perl (the @ARGV array) in-place. The function will by default replace characters that can't be decoded by "\x{FFFD}", the Unicode replacement character. Any argument provided is passed as CHECK to underlying Encode::decode() call. Pass the value "Encode::FB_CROAK" to have the decoding croak if not all the command line arguments can be decoded. See "Handling Malformed Data" in Encode for details on other options for CHECK. =item env( $uni_key ) =item env( $uni_key => $uni_value ) Interface to get/set environment variables. Returns the current value as a Unicode string. The $uni_key and $uni_value arguments are expected to be Unicode strings as well. Passing "undef" as $uni_value deletes the environment variable named $uni_key. The returned value will have the characters that can't be decoded replaced by "\x{FFFD}", the Unicode replacement character. There is no interface to request alternative CHECK behavior as for decode_argv(). If you need that you need to call encode/decode yourself. For example: my $key = Encode::encode(locale => $uni_key, Encode::FB_CROAK); my $uni_value = Encode::decode(locale => $ENV{$key}, Encode::FB_CROAK); =item reinit( ) =item reinit( $encoding ) Reinitialize the encodings from the locale. You want to call this function if changed anything in the environment that might influence the locale. This function will croak if the determined encoding isn't recognized by the Encode module. With argument force $ENCODING_... variables to set to the given value. =item $ENCODING_LOCALE The encoding name determined to be suitable for the current locale. Encode know this encoding as "locale". =item $ENCODING_LOCALE_FS The encoding name determined to be suiteable for file system interfaces involving file names. Encode know this encoding as "locale_fs". =item $ENCODING_CONSOLE_IN =item $ENCODING_CONSOLE_OUT The encodings to be used for reading and writing output to the a console. Encode know these encodings as "console_in" and "console_out". =back
