Utils.quote介绍

[英]Quotes a string if it contains special characters. The following rules are applied: A character is backquoted version of it is one of " ' % \ \n \r \t . A string is enclosed within single quotes if a character has been backquoted using the previous rule above or contains { } or is exactly equal to the strings , ? space or "" (empty string). A quoted question mark distinguishes it from the missing value which is represented as an unquoted question mark in arff files.
[中]如果字符串包含特殊字符，则将其引为引号。应用以下规则：一个字符是反引号，它的版本是“%\n\r\t”中的一个。如果一个字符使用上述规则反引号，或包含{}或与字符串、空格或“”（空字符串）完全相等，则字符串将被括在单引号内.带引号的问号将其与缺失值区分开来，缺失值在arff文件中表示为未带引号的问号。
