QXmlStreamReader Codec

[VRonin]

Noob question here:
Does QXmlStreamReader auto detect the text codec based on the start document (<?xml version="1.0" encoding="UTF-8"?>)? I noticed there is no setCodec method while QXmlStreamWriter has it so I want to make 100% sure it's dealt with automatically.

Hi! Yes, the codec is automatically set depending on the encoding attribute if QT_NO_TEXTCODEC is not defined. See qxmlstream.cpp:

#ifdef QT_NO_TEXTCODEC
                readBuffer = QString::fromLatin1(rawReadBuffer.data(), nbytesread);
#else
                QTextCodec *const newCodec = QTextCodec::codecForName(name.toLatin1());
                if (!newCodec)
                    err = QXmlStream::tr("Encoding %1 is unsupported").arg(name);
                else if (newCodec != codec && !lockEncoding) {
                    codec = newCodec;
                    delete decoder;
                    decoder = codec->makeDecoder();
                    decoder->toUnicode(&readBuffer, rawReadBuffer.data(), nbytesread);
                }
#endif // QT_NO_TEXTCODEC
