Encoding in QProcess output

[ODБOï]

@jsulm yes, but got same
@KroMignon i also tryed
QString output = QString::fromLocal8Bit(process->readAllStandardOutput());
but still same output

[jsulm]

@LeLev Try with std::cout instead of qDebug()

[KroMignon]

@LeLev Other thing I can suggest is to use qUtf8Printable()

 QObject::connect(process,&QProcess::readyReadStandardOutput,process,[&](){
            QString output = QString::fromLocal8Bit(process->readAllStandardOutput());
            QStringList lines = output.split("\\r\\n");
            QStringListIterator it(lines);
            while(it.hasNext()){
               qDebug() << qUtf8Printable(it.next())<< endl;
            }
        });

@jsulm i have never used it with Qt,i will try?My final aim is to write the output to a file.

@LeLev said in Encoding in QProcess output:

process->readAllStandardOutput())

To debug this, I'd suggest to print the output as hex:

qDebug() << process->readAllStandardOutput().toHex();

Then you need to find then code for 'é', which allows you to find the encoding used by your system. It may well be local 8 bit, UTF-8 or any of the encodings we used in the 1990. Before you don't know the exact codec, you cannot properly convert the output to a QString and therefore you cannot print it.

@KroMignon unfortunately the output is almost the same,.. i had :
? in place of é
now i have
, in place of é

Do you need to change encoding between reading and writing? if the answer is no you can just simply:

 QObject::connect(process,&QProcess::readyReadStandardOutput,process,[=](){
QFile outputLog("outputLog.txt");
if(!outputLog.open(QIODevice::Append | QIODevice::Text))
return;
outputLog.write(process->readAllStandardOutput());
});

@VRonin no i don't neet to change, i only want the output of command
ipconfig /all
inside a new file.
but sadly there is still issues in the file (outputLog.txt)..

I will try do debug this using what @aha_1980 said. On Monday. This is first time Qt, windows and coding pissed me off for real.

Thank you very much for help anyway

if i run my windows terminal directly and execute
ipconfig/all >> text.txt
it creates a text file with lot of encoding issues also.

Given that, should you set the proper encoding for the command line? See this post as it may help...

may help...

not realy ..

i tryed

REG ADD HKCU\Console /v CodePage /t REG_DWORD /d 0xfde9

failed, then :

Now we need to add a TT font that supports the characters you need like Courier New, we do this by adding zeros to the string name, so in this case the next one would be "000" :

    REG ADD "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Console\TrueTypeFont" /v 000 /t REG_SZ /d "Courier New"
Now we implement UTF-8 support:

    REG ADD HKCU\Console /v CodePage /t REG_DWORD /d 65001 /f
Set default font to "Courier New":

    REG ADD HKCU\Console /v FaceName /t REG_SZ /d "Courier New" /f
Set font size to 20 :

    REG ADD HKCU\Console /v FontSize /t REG_DWORD /d 20 /f

failed, then :

Save the following into a file with ".reg" suffix and execute

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Console\%SystemRoot%_system32_cmd.exe]
"CodePage"=dword:0000fde9

now if i open my terminal (cmd.exe) it will close instantly : any idea why ?

[ODБOï]

actually if i run cmd like this :
cmd /K chcp 65001
it will not close instantly and output is correct now.
So kind of solved, but broked "normal openning".. also if i type somethig wrong in it, i dont have error message, instead it closed immediatly
