Per Fozzer:
So how do you generate the characters "ae", "ue", and "oe", which overlap each other as in "Ae"sop's Fables....
Good Question. I've done it with a graphics program but that means generating it as a px, taking a lot of extra time. The name Alfred used to be 'Ae'lf(=Elf but now Alf in the name) 'raed'(=council); now it's gone the way of Aesop's fables.
Originally, one tried pronouncing both letters at the same time but the enunciation and the vocabulary went through major changes after 1066A.D. Did the pronunciation change cause the spelling change or, as seems more likely, the spelling change alter the pronunciation
