我在处理来自 QProcess 的 unicode 输出时遇到了一些问题。当我运行以下示例时,我得到 ?? 而不是中文。谁能告诉我如何获得 unicode 输出?
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 我尝试运行您修改后的代码,但出现错误:
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
