This is a nasty bug, which occurs on most software. The root cause of this
bug is that in Turkish there's two 'i' letters; one with point and one
without. So highercase 'i' is not 'I', instead '?'. And lowercase 'I' is not
'i', instead '?'.
Because of this difference, although code completition is case insensitive,
in Turkish regional settings, the members that start with 'i' and 'I' become
For example if class A has a member "public String INPUT", you can't see it
when you press 'i' and ctrl+space.
