On looking closer, 'x', octal digits, and '.' would also be trouble.
So I made it reject a-z, 0-9, and dot.
It appears that the CSV mode is a few bricks shy of a load here as

broken output. It seems we ought to forbid delimiter from matching CSV
quote or escape characters. I'll let you clean up that case though...
