Are you sure about that? If I understood the original patch
description correctly, Wine currently has the following mappings:
    İ -> i
    i -> I

    I -> i
    ı -> I

While the correct (Windows) mappings would be:

    with LCMAP_LINGUISTIC_CASING and tr or az locale:
        İ <-> i
        I <-> ı

    without LCMAP_LINGUISTIC_CASING:
        I <-> i
        İ   -> İ
        ı   -> ı

I think doing this properly would need to take the data from
http://www.unicode.org/Public/9.0.0/ucd/SpecialCasing.txt into
account. http://www.unicode.org/reports/tr44/#Casemapping seems
relevant.
