NAME

Lingua::Han::Utils - The utility tools of Chinese character(HanZi)

SYNOPSIS

    use Lingua::Han::Utils qw/Unihan_value csplit cdecode csubstr clength/;

    # cdecode
    # the same as decode('cp936', $word) in ASCII editing mode
    #         and decode('utf8', $word) in Unicode editing mode
    my $word = cdecode($word);

    # Unihan_value
    # return the first field of Unihan.txt on unicode.org
    my $word = "我";
    my $unihan = Unihan_value($word); # return '6211'
    my $words = "爱你";
    my @unihan = Unihan_value($word); # return (7231, 4F60)
    my $unihan = Unihan_value($word); # return 72314F60

    # csplit
    # split the Chinese characters into an array
    my $words = "我爱你";
    my @words = csplit($words); # return ("我", "爱", "你")

    # csubstr
    # treat the Chinese characters as one
    # so it's the same as splice(csplit($words), $offset, $length)
    my $words = "我爱你啊";
    my @words = csubstr($words, 1, 2); # return ("爱", "你")
    my @words = csubstr($words, 1); # return ("爱", "你", "啊")
    my $words = csubstr($words, 1, 2); # 爱你

    # clength
    # treat the Chinese character as one
    my $words = "我爱你";
    print clength($words); # 3

EXPORT

Nothing is exported by default.

EXPORT_OK

cdecode

use Encode::Guess to decode the character. It behavers like: decode('cp936', $word) under ASCII editing mode and decode('utf8', $word) under Unicode editing mode.

Unihan_value

the first field of Unihan.txt is the Unicode scalar value as U+[x]xxxx, we return the [x]xxxx.

csplit

split the Chinese characters into an array, English words can be mixed in.

csubstr(WORD, OFFSET, LENGTH)

treat the Chinese character as one word, substr it.

(BE CAFEFUL! it's NOT lvalue, we cann't use csubstr($word, 2, 3) = $REPLACEMENT)

if no LENGTH is specified, substr form OFFSET to END.

clength

treat the Chinese character as one word(length 1).
