I say that because other GTK2 applications have a normal behavior, even Lazarus applications when my system language is "English". Maybe an "if" would solve the problem; I just want to keep talking to someone who can guide me in the LCL changes without causing disasters. Mattias gave me an advice (thanks!), and I have found a new direction.

Mattias, thanks for your help.
I don't know how I can create a patch... everything I know is that I 
must download the sources from SVN, but I'm raw about these kind of task 
If I give some simple instructions, can you or somebody create it?

In _*lcl/interfaces/gtk2/gtk2proc.inc*_, line 2278, we have:


We just need to do the solution you gave (I created a new name for the 

{$IfDef GTK2LatinAccents}
    gtk_im_context_filter_keypress(im_context, AEvent);

Thanks, I hope it will be useful for some people asking in the forums!
