I am deeply and sincerely ashamed of myself.
The point is that i get that input string by splitting the string in
my textView ([[myTextView textStorage] string]) into sentences. During
that procedure i check every char if it is a sentence terminator (?!
or linebreak). And i do that by using the -characterAtIndex: method.
And the thing is that that method returns wrong characters if it deals
with unicode ones. Thanks Keary Suska for pointing that out to me.
I will now have to find another "unicode-safe" way to split the string
into sentences.
Thanks again for all your help.
And if you could give me a hint on how to safely get unicode chars at
a given position of a string, I'd be even more grateful :)
Timofey.

Maybe the lifetime of the local copy is less than what SQLite needs.
I see in your code that you're releasing the copy, but is SQLite
asynchronous and still needing the buffer to exist at that point?
If you don't use a copy of the arg string, but the original arg
itself, does that change anything?
If you intentionally leak the copy, by not releasing it, does that
change anything?
How about autoreleasing the copy, which defers the actual release
until later?
I'm not suggesting that any of these are fixes, just different
things to test and observe, that may lead to more clues.
