Izmir, Turkey

Is there some Turkish accent I don't know about, or did Google Maps add a tittle to this capital I?

Never mind, @Indra answered my question! https://en.wikipedia.org/wiki/Dotted_and_dotless_I

And if you ever want to handle this in OpenType, I use the proposal by @Adam Twardoch:

feature locl {
    language TRK exclude_dflt; # Turkish
        lookup I_TURKISH {
            sub i by i.TRK;
        } I_TURKISH;

    language AZE exclude_dflt; # Azeri
        lookup I_TURKISH;

    language CRT exclude_dflt; # Crimean Tatar
        lookup I_TURKISH;
} locl;

This way you can exclude the dotted i from being swallowed into ligatures when the dot is significant to the language.

If {smcp} is present, then one also has to consider including a TRK (et al.)–specific substitution mapping lowercase i to the dotted small cap.

If {smcp} is present, then one also has to consider including a TRK (et al.)–specific substitution mapping lowercase i to the dotted small cap.

What would that look like in the above code?

Just add
sub i.TRK by idotaccent.sc;
To your smcp feature.

Ah, happy memories of living in Ankara and learning Turkish back in the 1990s.
