I can't get the intention. > Do we really need this filter ? I believe there are two purposes to this filter: 1. To filter out values which would be implausible for a highway shield. That is, some refs look like "Autostrada del Sole", which would result in a shield displaying just "Autostrada", which isn't really desirable. 2. To remove spaces from plausible refs. As you noted above, intermediate spaces have to be removed from refs such as "B 1", as only "B" would be displayed in the shield. That said, the filter algorithm could certainly be improved. If I have time this week, I might try taking a few hacks at it. You could do the same, if this would amuse you. ;-) Cheers.
