禁則文字

When it comes to the beginning or end of a line, it is a character that is inappropriate in appearance or hard to read. Typical examples include punctuation marks and parentheses. There are two types of punctuation characters: line beginning and end line punctuation characters. The former refers to characters that are inconvenient to come to the beginning of the line, and the latter refers to characters that do not allow to come to the end of line.
