This is  a test
file called wc1 that has several sentences.
這是中文英文夾雜在一起的文字檔案，
I don't think that punctuation  inside
a character should be treated as a
separator.If the person type in a
sentence without giving it suitable
spaces,your program still have to
figure out the correct word count.
希望你能夠正確地處理，
For example, this paragraph has
441 characters, 65 words, and 13 lines,
共有 41 個中文字(不含全型的標點符號)。
