This has been a long time discussion about PTC not using their "best effort" in making these tables. I have a similar issue with UNC - 2 B... which should be UNC-2B.
If you bracket the characters with {0:&variable}MORE TEXT, you can remove the space delimiter. the problem is that the variables simply do not know where the variable name ends and the resumption of characters resumes. the string -does- know this when using the &... for the next variable.
