printing unicode through a QProcess
I'm having some trouble handling unicode output from a QProcess. When I run the following example I get ?? instead of 中文. Can anyone tell me how to get the unicode output?
from PyQt4.QtCore import *
def on_ready_stdout():
byte_array = proc.readAllStandardOutput()
print 'byte_array: ', byte_array
print 'unicode: ', unicode(byte_array)
proc = QProcess()
proc.connect(proc, SIGNAL('readyReadStandardOutput()'), on_ready_stdout)
proc.start(u'python -c "print \'hello 中文\'"')
proc.waitForFinished()
@serge I tried r开发者_如何学编程unning your modified code, but I get an error:
byte_array: hello Σ╕¡µ??
unicode:
Traceback (most recent call last):
File "python_temp.py", line 7, in on_ready_stdout
print 'unicode: ', unicode(byte_array)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe4 in position 6: ordinal
not in range(128)
I've changed your code a little and got the expected output:
byte_array: hello 中文
unicode: hello 中文
my changes were:
- I added # -- coding: utf-8 -- magic comment (details here)
- Removed "u" string declaration from the proc.start call
below is your code with my changes:
# -*- coding: utf-8 -*-
from PyQt4.QtCore import *
def on_ready_stdout():
byte_array = proc.readAllStandardOutput()
print 'byte_array: ', byte_array
print 'unicode: ', unicode(byte_array)
proc = QProcess()
proc.connect(proc, SIGNAL('readyReadStandardOutput()'), on_ready_stdout)
proc.start('python -c "print \'hello 中文\'"')
proc.waitForFinished()
hope this helps, regards
