Just a small contribution, because I tend to take from PADs communities more than I give.
So far, all the supportnet queries on using special characters I've seen are misleading. One says that after PADS 5, the "mu" symbol can't be used. Another says, that if you want special characters, you have to use a different font. This is untrue, and I'm a little disappointed at the lack of thoroughness of the proposed solutions, although not I'm no longer surprised
If you need a special character, and still prefer the stroke font, the attached table of special characters can be achieved using a combination of Alt + a three digit number.
