These QUtf8 / QUtf16 / QUtf32 structs were always defined in a private header (qstringconverter_p.h), so marking them as private is correct. Maybe findclasslist.pl only looked at classes marked as Q_*_EXPORT, while these structs are not marked as such (individual members are marked instead).

I agree. -- Dmitry Shachnev
