In this article titled Coptic Unicode , I cannot find which key or key combination is used to enter an epsilon!  

The keyboard images that show the Coptic character are here..(zip file)

the key next to the iota, the "U", is the epsilon. This keyboard and font take the ancient shape of coptic letter, more like uncial than the fonts we use in coptic liturgical books.
