The problem lies in the gutenprint package. This can be seen by running
the PPD driver directly:
$ LC_ALL=fr_FR.UTF-8 /usr/lib/cups/driver/gutenprint.5.2 cat
"gutenprint.5.2://bjc-MULTIPASS-MP150/expert" |egrep -e
'(Encoding)|(OpenUI.*StpQuality)'
*LanguageEncoding: ISOLatin1
*OpenUI *StpQuality/Qualité d'impression: PickOne
or by using the cupsGetServerPPD() function:
$ LC_ALL=fr_FR.UTF-8 python -c 'from locale import *; setlocale(LC_ALL,'');
import cups, os; c=cups.Connection();
ppdfile=c.getServerPPD("gutenprint.5.2://bjc-MULTIPASS-MP150/expert");
ppd=cups.PPD(ppdfile); os.unlink (ppdfile); print
ppd.findOption("StpQuality").text'
Qualité d'impression
(note that we did *not* call ppd.localize() here)
i.e. it is breaking rule 6 of the globalized PPD rules. The gutenprint
PPD driver needs to be fixed so that it does not use 8-bit characters in
option descriptions for globalized PPDs except in translated
descriptions added as part of the extension.
Whether it does this by providing untranslated option descriptions,
leaving it to applications to use the ppdLocalize() function to get
translations, or by "breaking" its translated strings in the main part
of the PPD so that they are 8-bit clean, one way or the other it needs
to be fixed.
Regarding reading out a full PPD and writing it back: no, it is not
necessary to do this. Please file bugs for whichever cases you can find
where this occurs, and it can be looked at later. However, it is not
causing the problem at hand.
Regarding keeping PPDs consistent when writing them back: indeed, I
realise this, and am working on a fix for this. However, I don't
believe it is the entire cause of the bug at hand -- although it may
have been the cause for this particular instance (we don't know).
