This bug is wishlist, not important. Or do you really think that
it "has a major effect on the usability of a package"?

It works in 0.7.92. There are also some other places where we could accept
unicode strings e.g. TagSection.__getitem__().

It's also much better to pass str objects, as unicode handling has memory leaks,
because we can not delete the temporary encoded object we create. You can pass
str objects easily in Python, e.g. dbus supports passing utf8_strings=True to
most methods to get a str-based object (dbus.UTF8String).
