Input unicode characters in jupyther notebooks from vscode

Dearests,

I succeeded in making vscode run jupyther notebooks and also make it understand julia language syntax.

(For those interested, I basically installed Python vscode extension + some small tweaks for syntax highlighting as suggested in https://github.com/julia-vscode/julia-vscode/issues/1620#issue-683938901).

Warning: the whole procedure could become soon more straightforward pending some relevant PRs.

Everything works fine but input unicode characters. If type \alpha [tab] in a code cell, it completes, but it does not render the α.

Any advice?
