Comment 3 for bug 1403476

From current qml implementation, we may have "*شمارهnnnشماره" displayed for key sequence "*#nnn#". This brings some problems when backspace and insertion in the middle come forward because it assumes each insertion always inserts one character only. After some more analysis on Android's implementation, key name localization is only effective on the displayed text on the button. This means we should not pass i18n.tr("*") but simply "*" for the keyPressed signal. This would also avoid previous one character per insertion problem.
