Depending on the phone and keyboard, I actually find it easier to use em and en dashes on mobile instead of the computer. Usually on mobile I can just hit the button for numbers/symbols and long-press the hyphen-minus, then select the appropriate alternate dash. Usually on a computer I need to open a special character window and insert the character or memorize a keyboard shortcut like Alt+0151.
internet.website is available to register but I checked a couple registrars and they all seem to have it as a premium domain that costs several thousand to register.
