Various comments need to continue using the enumdata.py names, as they associate data with particular enum members, but we can now correctly use the en.xml versions of their names when we report them, rather than the enum-friendly names we use in the code. Since this now means the data may stray outside plain ASCII - it'll be UTF-8-encoded - this implies replacing the QLatin1StringView()s of the code that formerly read this data with QString::fromUtf8().

"""Script to generate C++ code from CLDR data in QLocaleXML form
