When tooltip is not set for a QAction, its text is used (seemingly by remove "&"). However, this doesn't work in Chinese, because "Open &Menu" would be "打开菜单(&M)", so after conversion it's "打开菜单(M)", with an extra "(M)".
In Chinese locale, probably a regex substitution of "s/^(.*)(&[A-Za-z])(…)?$/\1\3/" is needed.
