Yes, something like this is happening. After
:g/[^ -~]/move 1
The file then loads quickly. If those 13 lines are moved to the end of the file
the file takes nearly 3 minutes to load.
However, using
vim -u NONE ++enc=latin1 file.txt
or
vim -u NONE -c "set fencs=latin1" file.txt
or setting fencs=latin1 in my .vimrc do not avoid the slowness. Starting vim
with just -u NONE then
:e ++enc=latin1 file.txt
does. I don't understand.
