I'm not using Mac keyboard however it did work properly before. I changed the Command key to my Ctrl-key. Until today, using this Ctrl key yield extremely odd characters. When pressing Ctrl-A yields å Ctrl-V yields √ Ctrl-C yields ç

And I have no idea where do these characters come from? So how could I fix this issue? Can anyone please help? Thanks.

EDIT
Here is my screenshot

It looks like you have accidentally configured your control key to be your alt key. Case in point: when I press alt+a, I get å. alt+v returns √, and alt+c gives us ç. Go into your settings and check again. They are located in System Preferences -> Keyboard -> Modifier Keys. Note: alt is also option.

Edit: I cannot duplicate this phenomena (see comments on this answer), so I will guess that the non-Apple keyboard is messing up the process somehow.

Thanks a lot. However no matter what I change, it will never become the command key again since I turn on the Keyboard Viewer and I saw that every time I assign a different key to command, it becomes option :(. Really don't know what to do now? Any suggestion? –  Chan Jan 11 '12 at 6:54
    
@Chan That is odd. Let me play around with mine and see if I can duplicate what's going on. –  Mahnax Jan 11 '12 at 6:55

@Chan No problem! Couldn't reproduce, so I updated my answer. –  Mahnax Jan 11 '12 at 7:01
    
Thanks anyway. I guess I have to buy a Mac keyboard then. But it's totally weird since I set command to no action before. The only thing I did before that was reboot the computer from the command line since it was freeze. Other that, I couldn't think of any reason that would cause this problem. –  Chan Jan 11 '12 at 7:07
