Description
When the following codes are executing, an error poped up with message : "Invalid character in the document".

There are some Chinese text encoded by UTF8 in the document, and the codes are:


XMLDocument.XML.clear;
XMLDocument.XML.LoadFromFile(XMLFilename);
XMLDocument.Active := True;

or

XMLDocument.XML.clear;
XMLDocument.XML.LoadFromFile(XMLFilename, TEncoding.UTF8);
XMLDocument.Active := True;

Once the XMLDocument.Active is set to True, the error poped up. I can image the problem is caused by TStrings and XMLDocument internal logic conflicted.

Because classic XMLDocument used TStrings as AnsiString list, but TStrings were replaced with "TUnicodeString", so the XMLDocument logic will get unicode string to "DECODE" again.....

Therefore this error will poped up..... Please fix it ASAP, because TXMLDocument is used very frequently.

Could you please attach sample project to reproduce your issue?

With Japanese environment, we have same problem.

But, could you please try this
  XMLDocument.LoadFromFile(XMLFilename);
instead of
  XMLDocument.XML.LoadFromFile(XMLFilename);
   or
  XMLDocument.XML.LoadFromFile(XMLFilename, TEncoding.UTF8);

As Takahashi mentioned, I found the way to make XML work in 10/3:

    Self.XMLDocument1.Active := False;
    SElf.XMLDocument1.XML.Clear;
    Self.XMLDocument1.LoadFromFile(TargetPath);
    Self.XMLDocument1.Active := True;

This way can make TXMLDocument1 load UTF8 encoded document well, and I agree this way
is one of the solutions.

But the situation I mentioned in 10/2 still exists, and there must be many Delphi programmers used
to load XML document with  

TXMLDocument.XML.Clear;
TXMLDocument.XML.LoadFromFile(XMLFile);
TXMLDocument.Active := True;

I think that the situation should be fixed.
