# NAME Encode::UTF8Mac - "utf-8-mac" a variant utf-8 used by OSX filesystem # SYNOPSIS use Encode; use Encode::UTF8Mac; # some filename from osx... my ($filename) = <*.txt>; # it is possible to decode by "utf-8" but... $filename = Encode::decode('utf-8', $filename); # => "poke\x{0301}mon.txt" (NFD é) # ^^^^^^^^^ 2 unicode strings: "LATIN SMALL LETTER E" and "COMBINING ACUTE ACCENT" # probably you want these unicode strings. $filename = Encode::decode('utf-8-mac', $filename); # => "pok\x{00E9}mon.txt" (NFC é) # ^^^^^^^^ single unicode: "LATIN SMALL LETTER E WITH ACUTE" # DESCRIPTION Encode::UTF8Mac provides a encoding named "utf-8-mac". On OSX, utf-8 encoding is used and it is NFD (Normalization Form canonical Decomposition) form. If you want to get NFC (Normalization Form canonical Composition) character you need to use [Unicode::Normalize](http://search.cpan.org/perldoc?Unicode::Normalize)'s `NFC()`. However, OSX filesystem does not follow the exact specification. Specifically, the following ranges are not decomposed. U+2000-U+2FFF U+F900-U+FAFF U+2F800-U+2FAFF [http://developer.apple.com/library/mac/\#qa/qa2001/qa1173.html](http://developer.apple.com/library/mac/\#qa/qa2001/qa1173.html) iconv (bundled Mac) can use this encoding as "utf-8-mac". This module adds same name "utf-8-mac" encoding for [Encode](http://search.cpan.org/perldoc?Encode), it encode/decode text with that rule in mind. This will help when you decode file name on Mac. See more information and Japanese example: [Encode::UTF8Mac makes you happy while handling file names on MacOSX](http://perl-users.jp/articles/advent-calendar/2010/english/24) # ENCODING - utf-8-mac - Encode::decode('utf-8-mac', $octets) Decode as utf-8, and normalize form C except special range using Unicode::Normalize. - Encode::encode('utf-8-mac', $string) Normalize form D except special range using Unicode::Normalize, and encode as utf-8. OSX file system change NFD automatically. So actually, this is not necessary. # COOKBOOK use Encode; use Encode::Locale; # change locale_fs "utf-8" to "utf-8-mac" if ($^O eq 'darwin') { require Encode::UTF8Mac; $Encode::Locale::ENCODING_LOCALE_FS = 'utf-8-mac'; } $filename = Encode::decode('locale_fs', $filename); If you are using [Encode::Locale](http://search.cpan.org/perldoc?Encode::Locale), you may want to do this. # SEE ALSO [Encode::Locale](http://search.cpan.org/perldoc?Encode::Locale) - provides useful "magic" encoding. [Unicode::Normalize::Mac](http://search.cpan.org/perldoc?Unicode::Normalize::Mac) - this module uses it internally. # AUTHOR Naoki Tomita # LICENSE This library is free software; you can redistribute it and/or modify it under the same terms as Perl itself.
