Language flags issue (shows the same flag) for countries with multiple languges

On a multi-language site where in the country Switzerland I can show the following languages:

de_CH
it_CH
fr_CH

The problem is however, that the current language switcher shows 3 times the same flag, and that's the flag for Switzerland. Would it not be better to show for de_CH the german flag, for it_CH the italian flag and for fr_CH the french flag? Since there is in reality no such thing as a flag for a language, I believe this is the best solution.

The way to solve it for example for Switzerland is to add this CSS to your templates CSS:

span.flag_de_CH {
background: url("../../../modules/assets/css/images/flags/plain/flag_germany.png") no-repeat 0 0;
}
span.flag_it_CH {
background: url("../../../modules/assets/css/images/flags/plain/flag_italy.png") no-repeat 0 0;
}
span.flag_fr_CH {
background: url("../../../modules/assets/css/images/flags/plain/flag_france.png") no-repeat 0 0;
}
