Python Qt QLineEdit weird encoding

I have a situation that has me puzzled. I have a QLineEdit in my interface so when I populate it with the following text 𐡀𐡌𐡓 𐡊𐡓' 𐡓𐡁 𐡀𐡁𐡓𐡄𐡌 𐡏𐡋 (it's aramaic) and I have the correct fonts installed on my machine so I can see the fonts in browsers and all but these fonts I had to install then myself so you might see some weird chars. 

self.editor = QtGui.QLineEdit(self)
self.editor.setText(𐡀𐡌𐡓 𐡊𐡓' 𐡓𐡁 𐡀𐡁𐡓𐡄𐡌 𐡏𐡋)

so in the editor field in the ui I can see the text correctly but when I try to re-extract that text I get something weird:

editor_text = self.editor.text()

here I get an exception:

print(editor_text)
UnicodeEncodeError: 'utf-8' codec can't encode character '\ud802' in position 0:     
surrogates not allowed

pprint(editor_text)
"\ud802\udc40\ud802\udc4c\ud802\udc53 \ud802\udc4a\ud802\udc53' "
'\ud802\udc53\ud802\udc41 '
'\ud802\udc40\ud802\udc41\ud802\udc53\ud802\udc44\ud802\udc4c '
'\ud802\udc4f\ud802\udc4b'

I tried doing:

editor_text = self.editor.text().encode(encoding='utf-8', errors='surrogateescape')
UnicodeEncodeError: 'utf-8' codec can't encode character '\ud802' in position 0:    
surrogates not allowed

What could I do to fix this, thanks

EDIT:

I have of course added the header

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

All I had to do was

print unicode(testQLineEdit.text())

  1. Add this to the source header:

    #!/usr/bin/env python
# -*- coding: utf-8 -*-

    You can read this thread: PEP Index

  2. In your aramaic character string, add 'u' to the above Python string to use in unicode mode like this:

    u' ܐܪܡܝܐ‎ '

    or

    u'Unicode String'

Completed code:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import sys
from PyQt4 import QtCore, QtGui
class exampleQMainWindow (QtGui.QMainWindow):
    def __init__ (self):
        super(exampleQMainWindow, self).__init__()
        testQLineEdit = QtGui.QLineEdit(self)
        testQLineEdit.setText(u'ܐܪܡܝܐ‎')
        print testQLineEdit.text()
        self.setCentralWidget(testQLineEdit)

app = QtGui.QApplication([])
window = exampleQMainWindow()
window.show()
sys.exit(app.exec_())

You can get variables from somewhere else like this:

text = u'ܐܪܡܝܐ‎'
testQLineEdit = QtGui.QLineEdit(self)
testQLineEdit.setText(text)
print testQLineEdit.text()

To force the string to Unicode, you can use unicode(String).

This is the test type of output to return text:

>> print type(unicode(testQLineEdit.text()))
<type 'unicode'>

>> print type(testQLineEdit.text())
<class 'PyQt4.QtCore.QString'>

>> print type(testQLineEdit.text().toUtf8())
<class 'PyQt4.QtCore.QByteArray'>

All conditions can print in the console.
