[PyQt] Problems with UTF-8 characters in UI / pyuic4

[Giuseppe Corbelli]

QT 4.6.3, PyQt 4.7.7, Windows XP, ActivePython 2.6.5

I have a form with a non-standard characted (the symbol for microliter). The
XML UI is something like:

<?xml version="1.0" encoding="UTF-8"?>
....
    <property name="text">
     <string>Ansa 1μl</string>
    </property>
....

The elementTree correctly parses the structure, however when I'm "compiling"
the UI with
uic.compileUi(source, pyfile, True)

I get an error:
Traceback (most recent call last):

_cstring
    return str(prop.text)
UnicodeEncodeError: 'ascii' codec can't encode character u'\u03bc' in position
2: ordinal not in range(128)

u"\u03bc" is the unicode for the symbol I was talking above (microliter)

I've found that in pyuic.uic.properties.py I have
def _cstring(self, prop):
        return str(prop.text)

It can be changed to
def _cstring(self, prop):
	if isinstance(prop.text, unicode):
            return prop.text.encode("UTF-8")
        else:
            return str(prop.text)

And this solves my issue ONLY IF the text is marked as "Translatable". If the
"Translatable" is OFF the prop.text is not unicode and so the string contains
some random shit depending on locale and whatever. This will need some more
work...
