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.
