This is a weird problem, I write a lot of different languages on my computer, and since my keyboard doesn't have all the keys in the world, I have made certain key-combinations that replaces them with another letter.
For example, "†˛" becomes "þ" and "∂∂" becomes "ð". Now that works fine, but I have also added "œœ" that is supposed to become "ǫ", but form some reason that special replacement does not work while the others do. EDIT: To be able to type the ǫ letter I must also press space ("œœ "), while the others work perfectly to write in a word without pressing space.
Is there any reason for this? I'm using the Yosemite 10.10.2, the same problem exists on the 10.0.3 DP.
