Minor-mode to add space between Chinese and English characters.
pangu-spacing-mode is an minor-mode to auto add space between Chinese
and English characters. Note that these white-space characters are not really
added to the contents, it just like to do so.
Take following sentance for example:
你好，我是coldnew，我喜歡使用emacs。
After you use pangu-spacing-mdoe, you will see
你好，我是 coldnew，我喜歡使用 emacs。
But the text doesn't be modify by this mode, after disable pangu-spacing-mode or use other text eidtor to open the file, you will still see:
你好，我是coldnew，我喜歡使用emacs。
pangu-spacing is named from pangu.js's README.
Translation of pangu.js's README [1]
If you are the one who feel quiet ill when see Chinese,
English and digits characters squeezed together and
want to add whitespace to separate them. This plugin (support
Chrome and Firefox) is what you need when surfing the
internet, it will add whitespace between Chinese,
half-width English, digits and symbols automatically.
These spaces between English and Chinese characters are called
pangu-spacing by sinologist, since it separate the cobnfusion
between full-width and half-width characters.
Studies showed that who dislike to add whitespace between
English and Chinese characters also have relationship problem.
Almost 70 percent of them will get married to the one they
don't love, the rest only can left the heritage to their cat.
Indeed, love and writing need some space in good time.
Let's go for it.

pangu-spacing-mode 是一個可以自動幫你將中文與英文之間加上空白作為分隔的 minor-mode, 他的名稱來自於 pangu.js 上的 README。
引述自 pangu.js README [1]
如果你跟我一樣，每次看到網頁上的中文字和英文、數字、符號擠在一塊，就會
坐立難安，忍不住想在它們之間加個空格。這個外掛（支援 Chrome 和 Firefox）
正是你在網路世界走跳所需要的東西，它會自動替你在網頁中所有的中文字和半
形的英文、數字、符號之間插入空白。
漢學家稱這個空白字元為「盤古之白」，因為它劈開了全形字和半形字之間的混
沌。另有研究顯示，打字的時候不喜歡在中文和英文之間加空格的人，感情路都
走得很辛苦，有七成的比例會在 34 歲的時候跟自己不愛的人結婚，而其餘三成
的人最後只能把遺產留給自己的貓。畢竟愛情跟書寫都需要適時地留白。
與大家共勉之。
