Thank you
I checked the XML tree example:
FDocTree := htmlParseFile(PAnsiChar(Utf8Encode(AFileName)), nil );
XML_TEXT_NODE, XML_CDATA_SECTION_NODE, XML_PI_NODE, XML_COMMENT_NODE:
begin
p := xmlNodeGetContent(xmlNode);
memoDetails.Text := Utf8Decode(p);
FreeMem(p);
end;
but i seems that can now show Chinese correctly on Chinese Windows.
The webpage is UTF-8 or GB2312 , they are Chinese Page, like www.baidu.com
The result memo show much ?? etc. not correct.
How do I change the code?
Thank you!
Bear
