*Important*: g.u and g.toUnicode are not always interchangeable. In fact,
you should use g.u to convert Qt QStrings to unicode. Here is an example
from quicksearch.py:
t = g.u(self.ui.lineEdit.text())
Similarly, g.ue should be used to convert Qt bytes to unicode. Here is an
example from LM.openZipFile:
s = theFile.read(name)
if g.isPython3:
s = g.ue(s, 'utf-8')
return StringIO(s)
Actually, the above code is dubious, because it will break if the mode of
the open command changes.
In addition, the code sometimes does s = g.u('aString'), but this isn't
really needed since Python 2.6(?) which supports unicode literals.
