Looking for reasons and solutions on the Internet, now posted here:

Illegal character exception when parsing xml file (even if the character is in a CDATA segment): Org.xml.sax.SAXParseException:An Invalid XML character (UNICODE:0XB) was fo und in the CDATA section.
The reason: according to the standards of the consortium, some characters cannot appear in the XML file:
0x00-0x08
0x0b-0x0c
0x0e-0x1f
When parsing XML, these characters are encountered with errors

Workaround:
For XML files that are likely to be problematic, the characters are filtered and then parsed.

Public static string stripnonvalidxmlchars (string str) {
  if ( str == null | | ". Equals (str)) {
    return str
  }
   Return str.replaceall ("[\\x00-\\x08\\x0b-\\x0c\\x0e-\\x1f]" ", ");
}
