[Keyboard] Any way to get the exact character typed

Hello,

is there any way to get the exact character which had been typed ?
I know that there are Events for Key_DOWN and so on. And i also know how
to check the modifiers. But so i have to implement all special
characters on the keyboard, or upper and lower case characters with the
shift modifier ?
Or is there any function in SDL for that ?

Thanks
