If both numeric format specifiers and "others" are used, assume we're dealing with a Qt-formatted message. In the case of Qt formatting (see https://doc.qt.io/qt-5/qstring.html#arg) only numeric formats are
replaced at all. This means (percentage: %1%) is valid (which was introduced in #9461), without needing any kind of escaping that would be necessary for strprintf. Without this, this function would wrongly detect %) as a printf format specifier (and an assertion triggers).
Also contains periodic translations update from Transifex.
