When calling a Webservice that is supposed to return a String with a special character (a kind of cross), I have the following error:
Caused by: javax.xml.stream.XMLStreamException: An invalid XML character (Unicode: 0x10) was found in the element content of the document.

How can I fix the problem ?
Thank you.
Apparently even though the encoding is valid, the XML document is not.
The only way I found was described in this article:
http://blog.mark-mclaren.info/2007/02/invalid-xml-characters-when-valid-utf8_5873.html
public String stripNonValidXMLCharacters(String in) {
StringBuffer out = new StringBuffer(); // Used to hold the output.
char current; // Used to reference the current character.
if (in == null || ("".equals(in))) return ""; // vacancy test.
for (int i = 0; i < in.length(); i++) {
current = in.charAt(i); // NOTE: No IndexOutOfBoundsException caught here; it should not happen.
if ((current == 0x9) ||
(current == 0xA) ||
(current == 0xD) ||
((current >= 0x20) && (current <= 0xD7FF)) ||
((current >= 0xE000) && (current <= 0xFFFD)) ||
((current >= 0x10000) && (current <= 0x10FFFF)))
out.append(current);
}
return out.toString();
}
