Take a look at the TZADE SOFIT of AL HA'ARETZ. The Yod part of the letter has no Yerech where it connects to the body of the letter. However, the YUD part does have a yerech on the right, just like a normal YOD would.
Are you of the opinion that one could possibly be makil on this, as the YOD part does have a YERECH. Or would this be a shinui in the shape of the letter, since there is no Yerech toward the side of the body, How would you consider this? Are there grounds to hold that the letter still retains its shape, and therefore consider it KASHER? Please don't be shy with your comments.
