I don't think there is a good way, because especially in the terminal
Vim won't know what the result of a character will actually look like.
Best way I can think of, put the character on the tabline. Then capture
the result and compare using `:echo nr2char(screenchar(1,1))`
That is probably nothing that can be done without the user noticing it
(e.g. it most likely requires a redraw for the tabline to be displayed
before capturing the result and then hiding and restoring the tabline
again).
Best,
Christian
