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'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
iconv (bundled Mac) can use this encoding as "utf-8-mac".
This module adds same name "utf-8-mac" encoding for 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
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'
) {
$Encode::Locale::ENCODING_LOCALE_FS
=
'utf-8-mac'
;
}
$filename
= Encode::decode(
'locale_fs'
,
$filename
);
If you are using Encode::Locale, you may want to do this.

Encode::Locale - provides useful "magic" encoding.
Unicode::Normalize::Mac - this module uses it internally.
