I can't get digraphs to work in vim.
When I type:
:digraphs
it gives me an error message: E196: No digraphs in this version.
Do I need to install any plugins or packages? If I type:
:scriptnames
it doesn't seem to return i.e. just seems to block.
I am using vim 8.2.587 in Fedora 30, running as a guest inside Virtual Box.
When using vim 8.2.158 running on a native Fedora 31 machine, the digraphs work fine.
Update:
vi --version | grep digraph
shows that vim was built with digraph support. The full output is below.
> vi --version

Small version without GUI and -digraphs speak a clear language here. Many Linux distributions just ship with a minimal, stripped-down version of Vim to provide vi compatibility. If you want to use the full Vim capabilities, you typically can install a separate package (usually named vim, or vim-full vs. the default vim-tiny). And that would then be invoked as vim, not vi.
