Weird text replacements on all apps on OS X I'm having a problem with the fonts on Mac OS X 10.10. I don't remember if I had this problem when I used 10.9, but I have it for more than a month now on 10.10.

So, in some applications, some groups of letters are being replaced by symbols: i.e. "fi" is replaced by a dot in Adium, and on Airmail 2 is replaced by a weirdly placed "e".

Here's a print form Adium: 



The actual text is: test: FIGARO figaro

And a print from Airmail 2:



There are more combinations of letters changing to different symbols, but I can't remember them right now.

Can somebody please tell me why is this happening? Thanks in advance!
I've solved the problem myself. I've installed a lot of fonts some time ago and some of them had already been installed by default, by OS X, and this created some conflicts which, apparently, caused my problem.

Hope it helps somebody else.
