I do notice a bug that another has also identified.
Up is translated as "yoopee". I'm not that good with the alphabet and linguistics. Is that a literal pronunciation of the two letters U. P.?
It is strange that "upon" actually gets it right but "up on" does not:
upon 𐐲𐐹𐐪𐑌 up on 𐐷𐐭𐐹𐐨 𐐪𐑌
This is a great site and am very interested in the inner workings. How do you do the translation? Do you have a data base of words (giant lookup table) or do you make a translation from English to sound equivalents and then from sound equivalents to Deseret? on matches. upon has correct rendering for up but up does not (has yoopee).
