I wonder if one could use a stroke-order method for writing the tengwar, such as stem + bow and bow + stem. u,w,n,m can be used for the bows, with a prefixed bar for closure? Then there's the puctuation thingies, etc etc...

I did used to have a perl script that created ASCII tengwar from text input. It worked sort of similar to the old 'banner' command (which I also had a perl script for).

\/^|-m or whatever.
