I thought it did recognize some of them? I'm really sorry but upgrading GOCR is very difficult, the way it's written. If it was simply a database, it would be easy to expand it, but it's not. It's all hard-coded in a large number of C-functions, each dedicated to detecting 1 or 2 characters!!! Unmanageable...
I'm not complaining though... It works really well *most* of the time...
