Replace the spaces with $chr(160)s.
Either use $chr(160) in your script, type them in manually (looks better, but harder to tell where you have used them) or use $str($chr(160),20) (where 20 is the number of $chr(160)s you want). The last is probably the best option because you will want to vary the number depending on the length of what you have read and your variables.
This may not work on some fonts.
