PyQt Unable to correctly print Unicode from `QProcess.readAllStandardOutput()`

[Please_Help_me_D]

Hi,

I don't fully understand how Unicode transformation is done and I've seen some topics (they helped me a bit) like this one
But still I'm going to clarify one thing:

I make a QProcess that should produce these symbols ℯαΔ.
Being more specific I make a call to julia programming language like this:

    self.qprocess.setProgram('julia.exe')
    self.qprocess.setArguments(['-E', '@info("ℯαΔ");'])
    self.qprocess.start()

  def onProcessReadyReadStandardOutput(self):
    print("QProcess output:\t", str(self.qprocess.readAllStandardOutput().data(), 'utf-8'))

The printed output is [ Info: ea?
The same output I get when running the same code from Windows powershell .\julia.exe -E '@info(\"ℯαΔ\")'

I believe the output that I get from python is affected by the fact that Windows command line doesn't support Unicode. Is that right?
Is there a way to avoid that and produce correct output from python?

@Please_Help_me_D said in PythonQt (PyQt) Unable to correctly print Unicode from `QProcess.readAllStandardOutput()`:

def onProcessReadyReadStandardOutput(self):
print("QProcess output:\t", str(self.qprocess.readAllStandardOutput().data(), 'utf-8'))

Try

def onProcessReadyReadStandardOutput(self):
    print("QProcess output:\t", str(QString(self.qprocess.readAllStandardOutput()), 'utf-8'))

@jsulm I'm sorry for the delay, haven't seen notification.

It seems that PyQt doesn't have QString class.
Is there a way to try it probably with QByteArray? Or something elese without QString

@Please_Help_me_D
Not my area, but there seem to be plenty of questions to look through from Googling print Unicode from QProcess.readAllStandardOutput()? E.g. maybe https://stackoverflow.com/questions/41761132/pyqt-qprocess-readallstandardoutput-encoding helps?

@JonB thank you for reply,

I tried googling that and tried to apply their solutions, but there was no way I could display alpha, beta, phi etc correctly.

Me neither I don't understand all that encoding staff. I only have some basic "knowledge" on that

(Just modified the title, because PythonQt is another project and for future readers, I hope they don't get it wrong when talking about PyQt)
