Warning: languages have different usages of punctuation, and sometimes they are swapped (e.g. openining and closing quotation marks, or full stop and colon in Armenian), or change their form (the full stop in Chinese and Japanese, the prefered "colon" in Armenian used in fact as the regular full stop, the comma in Arabic, Armenian, and Chinese...)
Their spacing (before or after) may also vary across languages (for example French requires a non-breaking space, preferably narrow if the browser supports NNBSP, on the inner side of some punctuations like quotation/question/exclamation marks, colon, and semicolons; for better line break handling in traditional & simplified Chinese, a zero-width space is added after the fullwidth "comma" as a soft line break without producing visual whitespaces).
