Usually while sending or receiving you will get invalid white space due to charset mismatch. You can create wrapper and try below code to resolve it.

/**
* From xml spec valid chars:<br>
* #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF]<br>
* any Unicode character, excluding the surrogate blocks, FFFE, and FFFF.<br>
* @param text The String to clean
* @param replacement The string to be substituted for each match
* @return The resulting String
*/
public static String CleanInvalidXmlChars(String text, String replacement) {
    String re = "[^\\x09\\x0A\\x0D\\x20-\\xD7FF\\xE000-\\xFFFD\\x10000-x10FFFF]";
    return text.replaceAll(re, replacement);
}
