I happened to find that we may open 'Terminal windows' in Vim and am happy to stop using terminal app. (It's available in v8 and v9)
However, when I have a typing mistake, pressing Delete key does not go backward and rub it out. Instead, it produces a strange letter 'ÿ'.
The only way I can fix such mistakes is pressing Ctrl-H (but this is tedious).
I cannot find documentation addressing this issue.
I tried to remap but both failed:
:tmap <ÿ> <c-h> :tmap <del> <c-h>
