qtspell/src/Codetable.cpp

Line 80 in 17a588f

name = QString::fromUtf8(dgettext(ISO_639_DOMAIN, name.toLatin1().data()));

qtspell/src/Codetable.cpp

Line 92 in 17a588f

name = QString::fromUtf8(dgettext(ISO_3166_DOMAIN, name.toLatin1().data()));;

Explanation:

You should replace these lines:

name = QString::fromUtf8(dgettext(ISO_639_DOMAIN, name.toLatin1().data()));

name = QString::fromUtf8(dgettext(ISO_3166_DOMAIN, name.toLatin1().data()));;

with these:

name = QString::fromUtf8(dgettext(ISO_639_DOMAIN, name.toUtf8().constData()));

name = QString::fromUtf8(dgettext(ISO_3166_DOMAIN, name.toUtf8().constData()));

or these:

name = QString::fromLocal8Bit(dgettext(ISO_639_DOMAIN, name.toLocal8Bit().constData()));

name = QString::fromLocal8Bit(dgettext(ISO_3166_DOMAIN, name.toLocal8Bit().constData()));
