$eval well be evaluated to null
This might work %text = $+($chr(2),$chr(2),$replacex(%text,$chr(32),$+($chr(32),$chr(2),$chr(2))))
Puts a double bold after each space (and at the start of the line), which should cause anything that might have been reevaluated (assuming a reevaluation occurs) to be seen as plain text
(might end up with a string to long error on big lines with lots of spaces)
