Bug Description

When installing kubuntu using the Greek language, in the Timezone selection screen,
there is a tooltip that shows the time and then supposedly "am" or "pm" but in Greek
case it shows gibberish instead of "πμ" or "μμ".

The reason is a hidden python str -> QString conversion since QString is latin-1 by
default.

One way to solve this problem is to add:

QtCore.QTextCodec.setCodecForCStrings(QtCore.QText.CodecForName("utf8"))

after

class TimezoneMap(QtGui.QWidget):

at

ubiquity/frontend/kde_components/Timezone.py

I would guess that this also affects other languages with non-latin alphabets
(e.g., Russian). Please fix.

I made a small mistake above :S

The correct line (as proposed in IRC by tsimpson) is

QtCore.QTextCodec.setCodecForCStrings(QtCore.QTextCodec.codecForName("utf8"))

Wow. QString is ISO-8859-1 by default, seriously? What decade is it again? :-)

Were you using the Python 3 port in 12.10 for this, or is this patch against 12.04? You don't mention which.

I think that if we make this change then it should be in the main KDE frontend code, to make sure it applies to the entire installer. But I'm quite surprised that this isn't picked up from the locale.

Hi,

It could also be python's problem to be honest, I 'm not so sure. The patch was for 12.04
(it should probably apply cleanly to 12.10's ubiquity but it was written with python 2.7
and 12.04 in mind).

Note to developers: you may need to 'sudo locale-gen el_GR.UTF-8' before starting ubiquity in order to reproduce this bug properly.

I have confirmed that this bug was naturally fixed by the new Python 3-based PyQt API used in 12.10, but I can still reproduce it in 12.04.

Tried an install in greek and I'm now getting am/pm so I guess that's good.
