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". |
