One of the reasons Twitter is popular in Japan is a characteristic of Japanese itself: Japanese uses ideograms which enable it to convey more information in just 140 characters than other languages, not counting Chinese. Incidentally, the Japanese version of this sentence is written with exactly 140 characters. How many characters does it take in other languages?

推特在日本之所以这么火，跟日语的性质有关。虽然可能比不上中文，但是跟其他大多数语言相比日语的140字可以承载更多的内容。顺带很想知道，这段文章正好是140字日文，换成别的语言的话会是多少字呢？
