Some readers may have been reading the thread entitled “Mandala - Circles” which is also in the Gallery forum.
Following my first post in that thread I tried some glyphs for ligatures ct and st in my Eutopian Architecture font and after the post by Bhikkhu Pesala with the example of the ty ligature in the Mandala - Circles thread, I tried a ty ligature in my Eutopian Architecture font. That attempt eventually resulted in just a t and a y a bit closer together, almost like a kerning pair. I feel that I gained some good experience by comparing the way that the ty ligature glyph in the Mandala font works with the way that a joined ligature appeared not to work in the Eutopian Architecture font and that design being abandoned, being replaced by the present design.
I have uploaded my working font Eutopian Architecture 415 to the web in case some readers might like to have a look at the present designs for a ct ligature and for an st ligature and the best that I could achieve for a ty ligature. I used the same mapping as Bhikkhu Pesala for the ty ligature. I added two copies of the ct ligature glyph, one that maps to U+E707 which is what I use for a ct ligature in most of my fonts and one that maps to U+EEC5. I realize that I could have used one copy of the glyph and mapped it twice, but I thought that it might be preferable to use two glyphs so that when I used Format Post… in FontCreator that both Postscript names would be displayed. I am unsure whether, had I mapped one glyph twice, both Postscript names would be in the font: and, if they were not, whether that could cause problems if the font were used to produce a pdf document using a software application. Maybe it was not necessary, but, as I do not at present know the answer to that problem, I thought it better to include the glyph twice.
