What was happening was that Vim is set to use "latin1", and using a

Vim then automatically switches off the conversion of Unicode to latin1
and you get the "raw" file.
If you set 'encoding' to "utf-8", this failure can't happen and it works
OK. Thus Vim is doing the right thing, there really was a conversion
error in that file when using "latin1".

Vim doesn't switch to using utf-8 automatically based on what file is
read. Changing 'encoding' has a lot of side effects (e.g., text in
registers may become invalid). I don't think changing 'encoding'
automatically is a good idea.
