That is a very bad idea. If a text has a Ꝭ in it, a Ꝭ should be displayed, not an IS. Particularly as in Middle English the correct reading might be ES, and in Middle Cornish the reading might be YS. > If anyone has any idea or example glyph from the period I'd love to see it, > but I doubt such exists :-) You are the type designer. You may live in the 21st century, but you could just as easily have lived in the 16th. Your client says “I need a Ꝭ glyph” and it’s up to you to design one. The easiest thing for your purposes (since you may not find a capital Ꝭ easily is to take the ꝭ glyph and modify it to fit between caps height and baseline. Cheers, Michael Everson
