Ah, yes of course, sorry, I was blindly looking at the result of xev.

It's libX11 and its XLookupString() function :)

Then maybe what I should just do is on the second event (for which
XLookupString gives me XK_A), remember the keycode, and when getting the
fourth event, notice that its the same keycode, and here realize that
the key was release (i.e. this time not match the keysym, but the
keycode)?
