Shouldn't the answer be tł'ízhí
Does the capital z make any difference or is this just a spelling error on the apps part???
It should be tł'ízí. The capital z is a typo.
(But there should not be an h.)
The z is okay. It is the mark between the ł and the í ( ʼ ) that is the problem. It isn't an apostrophe - so it often triggers a spelling error.
Why an upper-case "Z"?
How I solved it " Tt'iZi "
