Yes.

Mental acrobatics are part-and-parcel of the language, either in digital or non-digital form. If I were to spell out your name aloud, I would end with "ত-এ য-ফলা", which doesn't really say anything about how ত্য is pronounced. While writing on paper, we say "ক-এ ইকার", and then we reorder what we just said to write the ইকার in front of the ক. Even more complicated mental acrobatics - we say ক-এ ওকার, and then proceed to write half of the ওকার in front of the ক and then the other half, after the ক. We don't necessarily think about these when we carry out these acrobatics in our head, but they exist, and we have made the layer on top of the encoding system (rendering, and to some extent, input) deal with these acrobatics as well. My point in the original comment (and to some extent in the preceding one) was to emphasize that a lot of these issues are at the input method level - we should not have to think about encoding as long as it accurately and unambiguously represent whatever we want it to represent.
Just out of curiosity - I would be interested to know more about your learning experience that you feel is not well aligned with the representation of jophola as it is currently.
