Fixed bug #618
Description From Tim Angus 2008-08-30 12:23:56 (-) [reply]
As we all know SDL 1.2 doesn't handle dead keys well since one key press
potentially equals two (or more) characters. For example, on many layouts,
keying <backquote>,<space> results in <no character>,<backquote><space>. Since
the unicode member of the SDL_keysym struct only has room for one character,
only one can be returned.
On Linux, the first character is returned. On Windows however, unless the exact
number of characters generated by the keypress is 1, nothing is returned. The
following patch addresses this inconsistency.
Updated patch which includes a further fix to the handling of the numpad when
numlock is on. This further fix is courtesy Amanieu d'Antras.
