If text is going to be processed, i+dot is wrong for Turkish, as the
Unicode casing rules for Turkish will capitalise it to I+dot+dot, which
should display with two dots. If you're going to use an explicit dot,
I'd have said <U+0131, U+0307> would be better, though I still think
using an explicit dot is wrong in general.
