GRASS has never allowed 8-bit characters in the names of maps,
mapsets, locations, etc.

I'm not proposing that we lift that restriction, only that the rules
for vector maps be made consistent with the rest of GRASS. The sole
reason for the restriction was to avoid having to create a unique name
for the map's attribute table (although this would still be an issue
if you want to use a single database for multiple mapsets).
