Passing non-ASCII String value
I have downloaded Apache XML-RPC 1.2-b1, and tried to invoke a remote
service with the following code:
XmlRpc.setEncoding("UTF8");
XmlRpcClient client = new XmlRpcClient(url);
Object[] args = new Object[] { "__STRING__" };
client.execute("remote.method", new Vector(Arrays.asList(args)));
If __STRING__ contains non-ASCII(c < 0x20 || c > 0xff)-character, it
fails with a error "Invalid character data corresponding to XML
entity" at XMLWriter.chardata(String).
At XMLWriter.chardata(String) of CVS revision 1.2, it seems to just
pass the character to OutputStreamWriter.write(). Is that behaves
wrong? Why has it changed in 1.3 and 1.4?
Or is there another way to pass non-ASCII string for <string> value?

Thank you for your reply, John.

Sorry, that's right about values < 0x20. There is no problem that I
cannot send those characters. But about characters with values > 0xFF,
XML 1.0 allows it except for some special characters:
Char ::= #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] |
[#x10000-#x10FFFF]
http://www.w3.org/TR/REC-xml/#charsets
I think those should be allowed. The string I want to send only
contains Unicode characters defined in above.

It certainly should refuse to send characters with values less than
0X20 unless they are /n, /r or /t. The XML spec spec does not allow
these values in a well formed XML document.
If you need to send arbitrary binary data you will need to use Base64.
