The copy carries the scenario includes put in place of their include lines,
read as UTF-8 where they are, and it was written all in code page 1250. A name
with a Polish letter in a UTF-8 include then no longer matched the same name in
the files the simulator reads apart, and what 1250 lacks became '?'. Each part
now goes out in the encoding of the file it came from, the scenery's own file
too, as a save of a trainset already did.
