Utils.unbackQuoteChars介绍

[英]The inverse operation of backQuoteChars(). Converts back-quoted carriage returns and new lines in a string to the corresponding character ('\r' and '\n'). Also "un"-back-quotes the following characters: ` " \ \t and %
[中]backQuoteChars（）的逆运算。将带反引号的回车和字符串中的新行转换为相应的字符（“\r”和“\n”）。还有“un”-将下列字符反引：“\t和%
