':set fileencoding' and ':set encoding' with the _vimrc open both yield
'[...]=utf-8'. There is no BOM on the file, though a different Windows
encoding checker utility also reads the file as UTF-8.
UTF-8 is not the default &encoding. Make sure that you have
scriptencoding utf-8
set encoding=utf-8
before any other command in your vimrc. Remove &encoding setting that is
located somewhere else in your vimrc (it is located because utf-8 is not
the default).
Generally you just need to make sure you set &encoding before &listchars.
But it is better to use stricter rules specified above: make encoding
setting always the very first line in the vimrc, make the first line of
each script
scriptencoding utf-8

However, if I open and re-source the _vimrc (:so %), the file reads
without error, and listchars is set to the appropriate settings, Unicode
chars and all, and ':set list' works correctly.
