I'm using OsX Lion 10.7.4 version. Anyway when I try to type single quote then i, it prints í .. when i try to type double quote then i , it prints ï .. Looks like it's a setting but couldn't find how to change it.
It looks like;
Acute ´ option e + the character Á É Í Ó Ú á é í ó ú
But I'm not pressing option key.. Just pressing İ key on turkish layout with US English keyboard(Virtually)
How can I fix it?
