Comment 28 for bug 255372

just to let you know, i have the same problem with the slash and the question mark (also using an ABNT2 Keyboard - Brazilian)

this is the output for the Slash

KeyPress event, serial 31, synthetic NO, window 0x4400001,
    root 0x1a6, subw 0x0, time 158248712, (-67,108), root:(607,162),
    state 0x10, keycode 97 (keysym 0xff24, Romaji), same_screen YES,
    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False

KeyRelease event, serial 34, synthetic NO, window 0x4400001,
    root 0x1a6, subw 0x0, time 158248776, (-67,108), root:(607,162),
    state 0x10, keycode 97 (keysym 0xff24, Romaji), same_screen YES,
    XLookupString gives 0 bytes:
    XFilterEvent returns: False

and this is for the Question Mark (i have striped out the one for the Shift)

KeyRelease event, serial 34, synthetic NO, window 0x4400001,
