NAME

Lingua::HE::MacHebrew - transcoding between Mac OS Hebrew encoding and Unicode

SYNOPSIS

(1) using function names exported by default:

    use Lingua::HE::MacHebrew;
    $wchar = decodeMacHebrew($octet);
    $octet = encodeMacHebrew($wchar);

(2) using function names exported on request:

    use Lingua::HE::MacHebrew qw(decode encode);
    $wchar = decode($octet);
    $octet = encode($wchar);

(3) using function names fully qualified:

    use Lingua::HE::MacHebrew ();
    $wchar = Lingua::HE::MacHebrew::decode($octet);
    $octet = Lingua::HE::MacHebrew::encode($wchar);

   # $wchar : a string in Perl's Unicode format
   # $octet : a string in Mac OS Hebrew encoding

DESCRIPTION

This module provides decoding from/encoding to Mac OS Hebrew encoding (denoted MacHebrew hereafter).

Features

bidi support

Functions provided here should cope with Unicode accompanied with some directional formatting codes: i.e. PDF (or U+202C), LRO (or U+202D), and RLO (or U+202E).

expansion/contraction

e.g. decode("\xC0") returns "\x{F86A}\x{05DC}\x{05B9}" and encode("\x{F86A}\x{05DC}\x{05B9}") returns "\xC0".

Functions

$wchar = decode($octet)
$wchar = decodeMacHebrew($octet)

Converts MacHebrew to Unicode.

decodeMacHebrew() is an alias for decode() exported by default.

$octet = encode($wchar)
$octet = encode($handler, $wchar)
$octet = encodeMacHebrew($wchar)
$octet = encodeMacHebrew($handler, $wchar)

Converts Unicode to MacHebrew.

encodeMacHebrew() is an alias for encode() exported by default.

If the $handler is not specified, any character that is not mapped to MacHebrew is deleted; if the $handler is a code reference, a string returned from that coderef is inserted there. if the $handler is a scalar reference, a string (a PV) in that reference (the referent) is inserted there.

The 1st argument for the $handler coderef is the Unicode code point (integer) of the unmapped character.

E.g.

   sub hexNCR { sprintf("&#x%x;", shift) } # hexadecimal NCR
   sub decNCR { sprintf("&#%d;" , shift) } # decimal NCR

   print encodeMacHebrew("ABC\x{100}\x{10000}");
   # "ABC"

   print encodeMacHebrew(\"", "ABC\x{100}\x{10000}");
   # "ABC"

   print encodeMacHebrew(\"?", "ABC\x{100}\x{10000}");
   # "ABC??"

   print encodeMacHebrew(\&hexNCR, "ABC\x{100}\x{10000}");
   # "ABCĀ𐀀"

   print encodeMacHebrew(\&decNCR, "ABC\x{100}\x{10000}");
   # "ABCĀ𐀀"

CAVEAT

Sorry, the author is not working on a Mac OS. Please let him know if you find something wrong.

Maybe bug?: The (default) paragraph direction is not resolved. Does Mac always surround by LRO..PDF or RLO..PDF the characters with bidirectional type to be overridden?
