We have an application which uses a Code 39 font to print bar codes using
Crystal Reports. Unfortunately, it doesn't actually output the bar code for
the blank but prints a "real" blank instead, which results in an invalid bar
code.

Evidently, the '_' (underscore) character in the same font can be used to
output the bar code for the blank, but I don't see an easy way to do a
character substitution like this in a formula. Any Crystal wizards have an
insight to this one. If I could force it to use the actual blank from the
font, this would work too.
