~ is the tilde symbol for the hyphen.

Punctuation marks are symbols that assist written language recording and are an integral part of written language. They are used to express pauses, tone, and the nature and function of words.

There are 10 commonly used punctuation marks, divided into two categories: period marks and punctuation marks.

The function of the dot is to punctuate, mainly indicating pauses and tone when speaking. Dots are divided into sentence-ending dots and intra-sentence dots. The end-of-sentence period mark is used at the end of a sentence, and there are three types: period, question mark, and exclamation mark. It indicates the pause at the end of the sentence and also indicates the tone of the sentence. Intra-sentence dots are used within sentences, and there are four types: commas, pauses, semicolons, and colons, indicating various types of pauses within the sentence.

Periods, question marks, exclamation marks, commas, pauses, semicolons and colons generally occupy the same position as one character, located lower left and do not appear at the beginning of a line.

The first half of quotation marks, parentheses, and book title numbers do not appear at the end of a line, and the second half do not appear at the beginning of a line. The dash and the ellipsis both occupy the space of two characters and cannot be separated in between. Connection numbers and spacer numbers generally occupy one character. These four symbols are centered above and below.

Emphasis marks, proper title marks and wavy line book title marks are marked below the words and can be moved along with the words.
