No, please *don't* set fileencoding, encoding, or fileformats in your vimrc
at all. That's not where those settings should go and in fact you should
rarely need to set these settings. The default works just fine. I recommend
reading the documentation on what each one does. Online snippets like
StackOverflow and great for addressing specific needs but they are not good
for setting up a vimrc cohesively.
Setting 'encoding' etc. in the vimrc _may_ be a good idea if they aren't
yet set to utf-8 (this usually means on Windows but it might happen on any
weirdly set system). The snippet below, somewhere near the top of your
vimrc, will make sure that Vim, on any system, uses utf-8 internally, which
will allow it to process files in any encoding (for some unusual ones you
may have to tell it what to use in the :new or :edit command for the file,
see ":help ++enc"). This snippet is written using non-vim9 syntax; I've
liberally added comments (take them or leave them, they make of course no
difference to the snippet's working) to make it easier to understand.
" save the keyboard locale if defaulted to the same as 'encoding'
if == ""
let =

" if 'encoding' is not already some Unicode Transfer Format,

" * utf-8 should come next ; it will recognize files encoded in UTF-8

set fencs=ucs-bom,utf-8,default,latin1
" The following ('fenc' without the final s, defined globally) defines

" One advantage of UTF-8 is that files containing only characters

setg fenc=utf-8
