Chinese Word Breaking

When you write text in modern Chinese, there will not be any break between
different words, and thus if you segment characters according to the
ideographic characters, what being groupped together would either be a
clausee or a sentence, Or even a whole paragraph if you are handling some
older text without punctuations.

Also, that group of characters are not solely used by modern standard
chinese. For example, in Japanese there are expressions like 満を持す which
these four characters are generally treated as one word but as you can see
it is a mix of ideograph and hiragana. Similarly Taiwanese (nan) user would
also write latin alphabet together with these ideograph to form word. In
these cases if you change it to ID then what you are selecting would just
be part of the word.

And on character level you can't even tell what language the character is
written in, let alone telling apart which character is word or not. In
fact, in literal Chinese (lzh), most of these characters can be consider as
a word itself.
