This book (by Bök) is a good manual for all who want to build a hoard full of non-illicit (which is to say lawful and handy) words (although Bök, for a part, dips into a supply of that sinful glyph).

N.B. in Bök's colour chart, bán (or blanc, for my Franco pals) is that glyph this location bans. (Mark II) is a lipogrammatic Mastodon for all.
