Perl module to determine the locale encoding.
|
|
|
|
In 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".
