Hi Cheng,
You didn't show how the html variable was used? Are you sure that the html pointer is valid? I suggest: QByteArray ba = webView->page()->mainFrame()->toHtml().toUtf8(); const char *html = ba.constData(); ... In your original code, the temporary string and byte array were being destroyed after that statement, causing a dangling pointer in html. Even if it looked valid immediately after, subsequent allocations would have made the area appear corrupt. By keeping a reference to the temporary, you ensure that it will be valid for the whole block. Tony.

I want to add tidy as library into Qt program where I use some code as following: const char* html = webView->page()->mainFrame()->toHtml().toUtf8().constData(); // ... TidyBuffer output; Bool ok = tidyOptSetBool(tdoc, TidyXmlOut, yes); tidySetCharEncoding(tdoc, "utf8"); tidySaveBuffer(tdoc, &output); QByteArray ret = QByteArray(reinterpret_cast<char*>(output.bp),output.size); But I got warning: UTF-8 decoding error of 1 bytes : 0xff = U+0255lx UTF-8 decoding error of 1 bytes : 0xff = U+0255lx UTF-8 decoding error of 1 bytes : 0xe8 = U+0008lx UTF-8 decoding error of 1 bytes : 0xe8 = U+0008lx UTF-8 decoding error of 1 bytes : 0xfd = U+0001lx UTF-8 decoding error of 1 bytes : 0xfd = U+0001lx UTF-8 decoding error of 1 bytes : 0xfd = U+0001lx UTF-8 decoding error of 1 bytes : 0xfd = U+0001lx I've no idea how this happen.
