Yes, it seems to be independent of the XML. For instance, I get the same thing
when I run the little app below (the GUI is generated by pyuic4):
import sys
from PyQt4 import QtCore, QtGui
try:
_fromUtf8 = QtCore.QString.fromUtf8
except AttributeError:
_fromUtf8 = lambda s: s
class Ui_UTFWidget(object):
def setupUi(self, UTFWidget):
UTFWidget.setObjectName(_fromUtf8("UTFWidget"))
UTFWidget.resize(400, 300)
self.centralWidget = QtGui.QWidget(UTFWidget)
self.centralWidget.setObjectName(_fromUtf8("centralWidget"))
self.listWidget = QtGui.QListWidget(self.centralWidget)
self.listWidget.setGeometry(QtCore.QRect(17, 9, 362, 241))
self.listWidget.setObjectName(_fromUtf8("listWidget"))
UTFWidget.setCentralWidget(self.centralWidget)
self.menuBar = QtGui.QMenuBar(UTFWidget)
self.menuBar.setGeometry(QtCore.QRect(0, 0, 400, 22))
self.menuBar.setObjectName(_fromUtf8("menuBar"))
self.menuUTF_test = QtGui.QMenu(self.menuBar)
self.menuUTF_test.setObjectName(_fromUtf8("menuUTF_test"))
UTFWidget.setMenuBar(self.menuBar)
self.mainToolBar = QtGui.QToolBar(UTFWidget)
self.mainToolBar.setObjectName(_fromUtf8("mainToolBar"))
UTFWidget.addToolBar(QtCore.Qt.TopToolBarArea, self.mainToolBar)
self.statusBar = QtGui.QStatusBar(UTFWidget)
self.statusBar.setObjectName(_fromUtf8("statusBar"))
UTFWidget.setStatusBar(self.statusBar)
self.menuBar.addAction(self.menuUTF_test.menuAction())
self.retranslateUi(UTFWidget)
QtCore.QMetaObject.connectSlotsByName(UTFWidget)
def retranslateUi(self, UTFWidget):
UTFWidget.setWindowTitle(QtGui.QApplication.translate("UTFWidget",
"UTFWidget", None, QtGui.QApplication.UnicodeUTF8))
self.menuUTF_test.setTitle(QtGui.QApplication.translate("UTFWidget",
"UTF test", None, QtGui.QApplication.UnicodeUTF8))
class MyForm(QtGui.QMainWindow):
def __init__(self, parent=None):
QtGui.QWidget.__init__(self, parent)
self.ui = Ui_UTFWidget()
self.ui.setupUi(self)
self.ui.listWidget.addItem("abcde")
self.ui.listWidget.addItem("áɬʔéí")
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
myapp = MyForm()
myapp.show()
sys.exit(app.exec_())
notice that there are two additem() methods, one which adds straight ASCII, the
other which adds some non-ASCII characters. When I run the app, I see the first
(abcde) in the list widget and don't see the second (áɬʔéí). No XML involved.
