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).
