I'll try to check out your patch. In the meantime, I have another
related patch, which may be interesting for those wishing to use the
highway symbols.

I found out how to do regexes in Java, and added coding to
Element.java which performs the following:

- Removes the highway symbols from unreasonable names. (Names which
are too long, non-numeric, etc.)
- Removes spaces from names, so that they can be properly displayed as
highway symbols (Changes "A 1" to "A1", "SR 32" to "SR32", etc.)

This seems to correctly work for about 95% of all cases which I have
encountered.

The code is still a hack, and is far from optimal, but it may be
useful when implementing a proper solution. I'd be interested in
feedback.

Cheers.
