Is there any available library for word-counting of some hieroglyphics language (ex: chinese, japanese, korean...)?
I found that MS Word count effectively texts in these languages. Can I add reference to MS Word libraries in my .NET application to implement this function?
Or is there any other solutions to achieve this purpose?

Hieroglyphics? No, they're not. They're logographic characters and it's not so subtle difference. I'm sure some native speaker may explain this much better than me.
Japanese and Chinese text is made of characters exactly as western languages but one character may be a word to. Moreover they don't need spaces to separate words so our distinction characters/words can't be made using blanks as delimiters.
What Word does is to count words (assuming they'll be equal to characters) and you can do the same in your code (just don't forget it's UNICODE so you can't count bytes) counting characters. To count real words you need a dictionary (because you can't rely on spaces).
For example these strings:
这是一个示例文本
これは、サンプルのテキストです
Will be counted as 8 characters and 8 words (in Chinese) and 15 characters and 15 words in Japanese. Actually it's not (for example in Japanese it's 5 words when transliterated in romaji). Moreover don't forget in Japanese they have more than one alphabet (and one family of them are phonetic).
What's the point? What you will count? Words transliterated to one of phonetic representations (with latin characters) we use to represent them? Which one? Word counting will be pretty different and it'll actually count our concept of words (that's why, I suppose, Word counts characters).
That said now try to write this code:
string text = "这是一个示例文本";
MessageBox.Show(text.Length.ToString());
It'll display 8, as Word does (we're counting characters), in bytes (supposing an UTF-8 encoding) is 24. No sense to count spaces here. If you plan to count words in one transliteration you need to use an external library (it's not an easy task to do it by yourself), a different one for each language you want to support (somehow it's easy to auto detect the language because in Japanese they use very often hiragana/katakana characters). Which one? There are a lot of them, I don't know for Chinese but in Japanese a popular one to transliterate Kanji is Kakasi.
Korean is a complete different story, it's an alphabet exactly as latin one but character (that should be called syllable) may be composed of many letters. Again they don't need spaces so you can't rely on them for word counting. It's somehow more complicated because here you may need a dictionary even for character counting (otherwise you'll just count syllables).
