Illegal unquoted character ((CTRL-CHAR, code X)): has to be escaped using backslash to be included in string value

报错

Illegal unquoted character ((CTRL-CHAR, code 9)): has to be escaped using backslash to be included in string value

查看是哪个字符导致的

System.out.println(new String( Character.toChars(9) ));

纠错

把这个字符替换掉即可。

str = str.replace( new String( Character.toChars(x) ),"");

我的code 9是制表符\t导致的问题，.replaceAll("\t", " ")或.replace( new String( Character.toChars(9) ),"")替换掉即可，同理其他的\r、\n替换掉即可。
