Other than \0 which is the null terminator, can the use of control characters in strings cause weirdness with Sourcemod itself?

My plugin deals with player names, and I need at least 1, preferably 2, characters which cannot be used in a player's name.

My tests show that BEL (\7) works fine for my purposes... but is this a bad idea?

the low numbers indicate chat colors in several games

Very true! I'm going to move forward with this then; none of these strings will be printed to the chat or anywhere else, so that shouldn't be an issue.
