Irish script traditionally used a dot-less "i", something that persists in current road signage (anecdotally to save confusion with "í", or with adjacent old-style dotted consonants, I can't find a definitive source to cite). It's only an orthographic/type thing, it's semantically an "i", though the Unicode dot-less "i" is sometimes used online to represent it.
