You may want to use an emdash instead of the double hyphen. Hyphens are the undocumented text emphasis tag, strikethrough, so if you put double hyphens around words, it just looks -like this-. (Also, emdashes are single characters instead of pairs, so they take up two fewer characters for your total.)

To use the emdash, on Windows, hold down the Alt key and hit 0 1 5 1 on your keypad.

You can also use ellipses with Alt + 0 1 3 3: … Three dots, single space.
