Got off the encoding

[Ruzik]

Hellow, i have some problem:
if a try to do it:
@textEdit->append(process->readAllStandardOutput());@
//process is object of QProcess
i get it:
bq. “áâ ­®¢ª á¢ï§¨ á CORBINA...
à®¢¥àª ¨¬¥­¨ ¨ ¯ à®«ï ¯®«ì§®¢ ⥫ï...
¥£¨áâà æ¨ï ª®¬¯ìîâ¥à ¢ á¥â¨...
“áâ ­®¢«¥­ á¢ï§ì á CORBINA.
Š®¬ ­¤ ãᯥ譮 § ¢¥à襭 .

behind normal text, i try use toAscii(), toLocal8bit(), toUtf8(), toLatin1(), but i dont get normal text, how can i do it?
Advance many thanks for your help!

The problem is probably not in the conversion from QString, but in the conversion to QString. The QProcess::readALlStandardOutput() function returns a byte array. You have to convert that to a QString using the proper encoding using one of the QString::from*() variants, or even explicitly stating an encoding. Probably you could go for QString::fromLocal8Bit(), but I'm not sure about that.

What kind of text does the process output?

@Franzk
Seems like russian text in win cp1251 (or, oh god, cp 866) encoding :D

@Ruzik try toLocal8bit() to local QString, after it try using QTextCodec class for correct encoding

[Ruzik]

I try use all QString::from*, but it is donr work

bq. What kind of text does the process output?

I think, that it is must output russian text, as think Vass

bq. Ruzik try toLocal8bit() to local QString, after it try using QTextCodec class for correct encoding

I try do it, but i get other strange simbols instead of normal signs:
@ QString str;
QByteArray bArray = process->readAllStandardOutput();
str = QString(bArray).toLocal8Bit();
QTextCodec * tc = QTextCodec::codecForLocale();
if(tc->canEncode(str))
textEdit->append(tc->toUnicode(bArray));@

You are worried about the outgoing encoding, but you forget the incoming encoding. This code makes no sense at all.

Get your incoming encoding right:

@ // untested
QTextCodec *codec = QTextCodec::codecForLocale();
QByteArray bytes = process->readAllStandardOutput();
QString str = codec->toUnicode(bytes);
textEdit->append(str);
@

While you're at it, check if codecForLocale() is actually the codec you need.

[Ruzik]

bq. While you’re at it, check if codecForLocale() is actually the codec you need.

It seems that no,

That of course implied that you find out what encoding the external process uses to output it's text. Does it look OK when you run the application in a console? Does the application documentation say anything about it?

[Ruzik]

Process - rasdial.exe in Windows(http://msdn.microsoft.com/en-us/library/aa377004(v=vs.85).aspx )
Output on the russian language(on the my computer), but i dont know encoding of this process

[Franzk]

There is a slight possibility that that program outputs utf16 encoded data. Just using the byte array won't bu sufficient then. I'm not sure how to find out whether it does, though.

[Ruzik]

bq. I’m not sure how to find out whether it does, though

I try to ask it by Microsoft))

[Ruzik]

Microsoft didnt get me answer, i think that Vass was right, it is CP1251(Windows-1251)

[Ruzik]

I found that it is may CP1251 or koi8-U

[Franzk]

Consider choosing that locale explicitly:

@QTextCodec *cp1251 = QTextCodec::codecForName("Windows-1251");
QTextCodec *koi8u = QTextCodec::codecForName("KOI8-U");
@
for example, and see if that makes a difference in converting the string to unicode/QString.

[Ruzik]

Yes, it makes a difference in converting the string to unicode/QString
Windows-1251:

[Ruzik]

I find it, it was CP866
Many thanks for your help!
