QWebView doesn't display correctly unicode

**binaural** · 2nd September 2010, 13:02

well when open and read by python there are utf-8 encoded characters:
<html>\n<head><title>\xc4\xbe\xc5\xa1\xc4\x8d\xc5\ xa5\xc5\xbe\xc3\xbd\xc3\xa1\xc3\xad\xc3\xa9\xc3\xa 4\xc3\xba\xc3\xb4!!!</title>\n<meta http-equiv=Content-Type content=text/html; charset=UTF-8>\n</head>\n<body bgcolor='blue'>\n<center><H1>\xc4\xbe\xc5\xa1\xc4\ x8d\xc5\xa5\xc5\xbe\xc3\xbd\xc3\xa1\xc3\xad\xc3\xa 9\xc3\xa4\xc3\xba\xc3\xb4</H1></center>\n<hr>\xd0\x9f\xd1\x80\xd0\xb8 \xd0\xb4\xd0\xbe\xd1\x81\xd1\x82\xd1\x83\xd0\xbf\x d0\xb5 \xd0\xba \xd1\x81\xd0\xb0\xd0\xb9\xd1\x82\xd1\x83 \xd0\xbf\xd1\x80\xd0\xbe\xd0\xb8\xd0\xb7\xd0\xbe\x d1\x88\xd0\xbb\xd0\xb0 \xd0\xbe\xd1\x88\xd0\xb8\xd0\xb1\xd0\xba\xd0\xb0. \xd0\x9f\xd0\xbe\xd0\xb6\xd0\xb0\xd0\xbb\xd1\x83\x d0\xb9\xd1\x81\xd1\x82\xd0\xb0 \xd0\xbf\xd1\x80\xd0\xbe\xd0\xb2\xd0\xb5\xd1\x80\x d1\x8c\xd1\x82\xd0\xb5 \xd0\xb2\xd0\xb0\xd1\x88\xd0\xb5 \xd0\xbf\xd0\xbe\xd0\xb4\xd0\xba\xd0\xbb\xd1\x8e\x d1\x87\xd0\xb5\xd0\xbd\xd0\xb8\xd0\xb5 \xd0\xba \xd0\xb8\xd0\xbd\xd1\x82\xd0\xb5\xd1\x80\xd0\xbd\x d0\xb5\xd1\x82\xd1\x83.\n</body>\n</html>

so encoding should be correct.

I meant the file from my example. Besides I can't really see the utf-8 encoding among this garbage

What file you mean from your example?
OK start from beginning:
I create a file index.html with utf-8 encoding and also save file as utf-8:

Qt Code:

Switch view

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
</head>
<body>
<h1>Ä¾Å¡ÄÅ¥Å¾Ã½Ã¡Ã*</h1>
</body>
</html>

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
</head>
<body>
<h1>Ä¾Å¡ÄÅ¥Å¾Ã½Ã¡Ã*</h1>
</body>
</html>

To copy to clipboard, switch view to plain text mode

The use this code to display content (web is filename):

Qt Code:

Switch view

QTextStream in(&web);
in.setCodec("utf8");
view->setHtml(in.readAll(), QUrl("file:///home/www/"));

QTextStream in(&web);
in.setCodec("utf8");
view->setHtml(in.readAll(), QUrl("file:///home/www/"));

To copy to clipboard, switch view to plain text mode

but on display I can see only Ã½Ã¡Ã*.

The one with the label code. I suggest you start with getting that to work.

Well problem found. Problem was in font type. It seems unicode font doesn't support special characters. After enabling freetype text is correctly displayed.

Aren't you mixing two terms here? "Unicode font" is not about font format, it's about font encoding. Freetype fonts are "unicode fonts" too.

Yes maybe I wasn't precise. I was playing with fonts and if I don't compile freetype support to qt default font for displaying was family unifont (unifont_160_50.qpf). After installing truetype default font became (Dejavu Sans) which could correctly display all character which I need. I would say that unifont doesn't contain all special character.

With Dejavu Sans font text is correctly displayed but default font weight is bigger like for unifont and items are shifted. I try to change font weight by:

Qt Code:

Switch view

QFont web_font("DejaVu Sans", 6);
 
qDebug() << font.weight() << " " << font.pointSize();
 
web_font.setPointSize(6);
web_font.setWeight(20);
view->setFont(web_font);

QFont web_font("DejaVu Sans", 6);

qDebug() << font.weight() << " " << font.pointSize();

web_font.setPointSize(6);
web_font.setWeight(20);
view->setFont(web_font);

To copy to clipboard, switch view to plain text mode

but there's no effect (text has same weight and size). Is there any option which I'm missing to set?

Thanks

.qpf fonts are bitmap fonts. But you can generate your own .qpf from a font of your choice so I guess you can make one from DejaVu Sans and have proper glyphs available in .qpf.
