Example:
For
input[type="radio"] {
width: 15px;
width: 18px \0;
height: 15px;
height: 18px \0;
border-radius: 1em;
}
CSSlint is decoding the \0 as null character and writing it in the output XML file for a rule violation "Expected end of value but found".
Having a null character makes the output xmlfile invalid (not utf-8)
