This type?
But anyway I think the English first person singular nominative pronoun better be capital because of mentioned before fact that it contains only one character. It really gets lost as a lowercase character in ordinary texts. ik or yo or je or ich have one of the 2 or 3 characters with an "extension", making the word better noticeable.
For other languages it's too much work to find out what they all look like. Sorry. Maybe specialists pull it out if their sleeves just like that.
