If you’re on a Mac or iOS, it’s extremely easy to use the global text substitution to replace three periods (..., v...) with ellipsis (…, ⋮), and other symbols ((c), (r ), ^o, etc.) with their Unicode equivalent (©, ®, °, etc.).

Once upon a time there was COMPOSE.exe on Windows, then allchars, and now we've come full-circle to wincompose:

Ellipsis, at least, has been trivial to type (alt-semicolon) since long before global text substitution existed…

Most special characters are easily typed, either on a Mac keyboard using option, or on an International Windows keyboard with similar standards.
