><P
>Enables/Disables Unicode keyboard translation.</P
><P
>To obtain the character codes corresponding to received keyboard events,
Unicode translation must first be turned on using this function. The
translation incurs a slight overhead for each keyboard event and is therefore
disabled by default. For each subsequently received key down event, the
<TT
CLASS="STRUCTFIELD"
><I
>unicode</I
></TT
> member of the
<A
HREF="sdlkeysym.html"
><SPAN
CLASS="STRUCTNAME"
>SDL_keysym</SPAN
></A
> structure
will then contain the corresponding character code, or zero for keysyms that do
not correspond to any character code.</P
><P
>A value of 1 for <TT
CLASS="PARAMETER"
><I
>enable</I
></TT
> enables Unicode translation;
0 disables it, and -1 leaves it unchanged (useful for querying the current
translation mode).</P
><P
>Note that only key press events will be translated, not release events.</P
