Supplemental unicode characters are casted to char in the fatal error message
------------------------------------------------------------------------------
Key: XERCESJ-1064
URL: http://issues.apache.org/jira/browse/XERCESJ-1064
Project: Xerces2-J
Type: Bug
Components: Serialization
Versions: 2.6.2
Reporter: Serghei Balaban
Priority: Minor
Invalid supplemental characters can be larger than 0xFFFF. Therefore invalid
supplemental characters should not be casted to char type in surrogates(int
high, int low) methods of BaseMarkupSerializer and XML11Serializer classes :
protected void surrogates(int high, int low) throws IOException{
if (XMLChar.isHighSurrogate(high)) {
if (!XMLChar.isLowSurrogate(low)) {
//Invalid XML
fatalError("The character '"+(char)low+"' is an invalid XML
character");
}
else {
int supplemental = XMLChar.supplemental((char)high, (char)low);
if (!XMLChar.isValid(supplemental)) {
//Invalid XML
fatalError("The character '"+(char)supplemental+"' is an
invalid XML character");
}
else {
if (content().inCData ) {
_printer.printText("]]>&#x");
_printer.printText(Integer.toHexString(supplemental));
_printer.printText(";<![CDATA[");
}
else {
printHex(supplemental);
}
}
}
} else {
fatalError("The character '"+(char)high+"' is an invalid XML
character");
}
}
