Hey Robert, please please don't take away that hyphen
from my waypoint names! It is valid on my GPS12 and
rather needed given the limited character set :)
The Garmin spec says upper case letters and numbers
are a *minimal* character set supported by all Garmin
GPS for waypoint names.
The hyphen is included in each of the 3 Garmin
character sets defined in
http://www.topografix.com/gps.xml so it is probably
only ancient models that don't support the hyphen.
Those 3 Garmin character sets could even be a basis
for a GPSBabel option.

I'm getting _really_ frustrated at the Garmin protocol.
They won't document which characters actually _are_ legal, yet some
units do naughty things when they see ones that aren't legal. Aaaargh!

I'd flirted with that table, but as you observe, it directly conflicts
with Garmin's own doc. It lists 15 chars for the GPS V, but I'm pretty
sure that I counted 20. (I had one on loan; I could be wrong.)

Well, I wouldn't inflict it upon the user, but with dozens of models
supported and conflicting information which supports what, I'm kind of
at a loss how to get the code to do a sensible thing.
Additionally, I've heard rumours the 60's take a somewhat less
restricted set of characters, so the cheese is on the move again.
