Hi Zdenek,
\setdefaultlanguage{turkish} is the same as \setmainlanguage{turkish}
which is in my example and I tried, it doesn't have any noticeable effects.
However, \uccode`\i=`\I. gives the intended result but doesn't create
problems only because I'm working in a monolingual document, such type
of capitalization should be restricted to Turkish.
Thanks anyway, as far as my needs are concerned, this workaround
satisfies me.
