Lingua::ZH::Romanize::Pinyin - Romanization of Standard Chinese language


    use Lingua::ZH::Romanize::Pinyin;

    my $conv = Lingua::ZH::Romanize::Pinyin->new();
    my $roman = $conv->char( $hanji );
    printf( "<ruby><rb>%s</rb><rt>%s</rt></ruby>", $hanji, $roman );

    my @array = $conv->string( $string );
    foreach my $pair ( @array ) {
        my( $raw, $ruby ) = @$pair;
        if ( defined $ruby ) {
            printf( "<ruby><rb>%s</rb><rt>%s</rt></ruby>", $raw, $ruby );
        } else {
            print $raw;


Pinyin is a phonemic notation for Chinese characters.

$conv = Lingua::ZH::Romanize::Pinyin->new();

This constructer methods returns a new object with its dictionary cached.

$roman = $conv->char( $hanji );

This method returns romanized letters of a Hanji character. It returns undef when $hanji is not a valid Hanji character. The argument's encoding must be UTF-8. Both of Simplified Chinese and Traditional Chinese are allowed.

$roman = $conv->chars( $string );

This method returns romanized letters of Hanji characters.

@array = $conv->string( $string );

This method returns a array of referenced arrays which are pairs of a Hanji chacater and its romanized letters.

    $array[0]           # first Chinese character's pair (array)
    $array[1][0]        # secound Chinese character itself
    $array[1][1]        # its romanized letters


This module internally uses a mapping table from Hanji to roman which is based on PY.tit which is distributed with cxterm.


Storable module is required.


This treats utf8 flag transparently.
