As Miles said, you can call (ucs-unify-8859 t) to unify the latin
charsets when saving a file. Better yet: you don't need to do it any
more because it's now the default behavior.

That's what happens right now.

A German would get a prompt where iso-8859-2 and utf-8 should
be near the beginning of the list of coding-systems she can
choose from.

I don't know. All I know is that it's used when sorting coding-systems
so that the list has more "likely" coding systems at the beginning.
I think it's also used to choose more user-friendly names when a coding-system
has several aliases (such as mule-utf-8 and utf-8. Don't ask me why the
coding-system is called `mule-utf-8' and why `utf-8' is only an alias, tho).

I'm beginning to understand, thank you,
