Yes, this is something I overlooked.
Thanks for taking the patience to teach it to me.

That was my understanding, and this is the primary reason I answered your
post: I do not see the rationale to remove the ̇ after i and I, but not
after j.

I understand the rationale when it follows the i, but I fail to follow when it comes
to the I.
I am sorry to be so dumb, but you should take in account that I do not implement the
algorithm and I am just analysing the problem. There are probably very good reasons
to include the I as well, but they presently escape me.

As far as I know, no Lituanian material is expected to contain the sequence "İ"
(\u0049\u0307). Or am I overlooking something obvious?
