[Solved] XML coded in UTF-8 on Linux
I have written app which reads XML with QXMLQuery and using XQuery recieving data. But I am fighting for 2 days with encoding. Code:
@QFile sourceDocument( ":/xml/data.xml", this );
sourceDocument.open( QIODevice::ReadOnly );
m_query.bindVariable( "inputDocument", &sourceDocument );
QBuffer buffer( &outArray );
buffer.open( QIODevice::ReadWrite );
m_query.setQuery( query_str );
m_query.evaluateTo( &buffer );
QString result = QString::fromUtf8( outArray );@
Result string contains some numbers instead of special chatacters...
Please, can somebody tell me, how to process that UTF-8 XML ??

You're opening your file as binary, which I don't understand why, just wanted to point that out.
Then anyway, remember that for special characters, the stand ASCII decoding doesn't apply anymore. You have to to use 2 byte characters
Which are supported by standard C++ with char_w and other similar containers. Please read about that. For example, if I want to save some data with Arabic language, I have to save the whole file with 2 byte decoding.
I know that I need to use 2byte char.. I am sure that I dont need to use char_w with Qt, QString is working with UTF-16 by default.. and QFile does not mean that I am opening it as binary... I need to specify right codec for XML parser when it evaluates the query, because he messes up.. I am able to decode that XML into QString via QFile without corruption, but QXMLQuery does not support that I will pass the document as data, it wants to access the data itself.. and than it messes up encoding

Qt already handles UTF very well. There is no need whatsoever to use char_w here.
@adam.bogocz: I'm sorry, I don't know the answer to your actual question.

What's the result if you evaluate to a QString directly, instead of a QByteArray?
Hi Volker, passing QString into evaluate works well, conding is kept :) Thanks !
