Comment 9 for bug 9364

I'm not sure I understand this bug at all.
But if the sequence "i" and "j" cannot be "ij" all the time, why not simply set a
key for it?

Add the appropriate line in the file /etc/X11/xkb/symbols/pc/nl or replace it in
the keymap file you're using.
    key <AC07> { [ j, J, 0x01000133, 0x01000132] };

This way, pressing AltGr+j will give ij in almost any application in X.
