Is it possible to create Unicode files using Vim?

Yes. It may be more or less complicated depending on the keyboard and fonts available to you, but it is always possible to encode any possible Unicode codepoint (and some illegal ones) into a file. To create a Unicode file using Vim, you should have compiled Vim with the “+multi_byte” compile-time option. You can get more information about Unicode from the following sites: http://www.unicode.org https://www.cl.cam.ac.uk/~mgk25/unicode.html
