Punctuation two styles differ mainly in the way in which they handle quotation marks, particularly in conjunction with other punctuation marks. In British English, punctuation such as periods and commas are placed outside the closing quotation mark; in American English, however, punctuation is placed inside the closing quotation mark. This rule varies for other punctuation marks; for example, American English follows the British English rule when it comes to semicolons, colons, question marks, and exclamation points. Other languages of Europe use much the same punctuation as English. The similarity is so strong that the few variations may confuse a native English
Chinese punctuation from "halfwidth" European punctuation marks. Chinese characters can be written horizontally or vertically. Some punctuation marks adapt to this change in direction: the parentheses, square brackets, square quotation marks, book title marks, ellipsis marks, and dashes all rotate 90° clockwise when used in vertical text. The three underline-like punctuation marks in Chinese (proper noun mark, wavy book title mark, and emphasis mark) rotate and shift to the left side of the text in vertical script (shifting to the right side of the text is also possible, but this is outmoded and can clash with the placement of other punctuation marks).
