How to make vim always show the encoding of current opened file?

Question

Is there a way to configure vim to do this way?

Answer 1

You can set your GUI title, statusline, or ruler to show the information. See:

:help 'statusline'
:help status-line
:help 'laststatus'
:help 'rulerformat'
:help 'titlestring'

For example, you could do:

:set laststatus=2 statusline=%f\ %m\ %{&fileencoding?&fileencoding:&encoding}
