[mkgmap-dev] Testing for a literal question mark

How would I write a regex style rule that fires when it encounters a question mark in a name? There is a group of local mappers that have used an invented name of "Ban ?" for towns they do not know the name of. I want to set the name to something more meaningful but I can't seem to discover a way to escape the ? without crashing mkgmap. -- Dave Swarthout Homer, Alaska Chiang Mai, Thailand Travel Blog at http://dswarthout.blogspot.com
