Thanks, that is useful to know.

No, because (according to --help) the command is run after loading the
first file. Meanwhile, "--cmd <command>" does not work because it
runs the command before sourcing any vimrc file, and so, the new fencs
setting gets overwritten by the vimrc. It would be useful to have an
option to run a command just *before* loading the first file but after
any rc-files.

I don't include utf8 in my default fencs setting because that has the
side effect of using utf8 for any newly created files.
