# Windows in German display language outputs LATIN1 bytes for .zone, but marks them as
# IBM437, which somehow fails any attempt at conversion to other encodings when
# ä is present, as in the timezone name "Mitteleuropäische Zeit" (Central Europe Time)
#
# Windows-1252 is the legacy encoding for Windows for German that actually
# translates (ISO-8859-1 works as well), but going with the more correct
# encoding name for Windows' implementation of Latin-1
