* Outputs: buttons - Sequence of buttons to press.

* Description: The standard comment format uses the multipress
* encoding which allows only single case letters, digits,
* and the space character.
* This is a more flexible format that can handle all
* printable ASCII characters. We take the character code,
* subtract 32 and convert to two decimal digits. i.e.
* space = 00
* ! = 01
* " = 02
* ...
* ~ = 94
*
* This is mostly for internal use, so macros can generate
* comments with all characters.
