Issues with ACIP to Unicode Conversion and MacOSX

I'm really having fun with Unicode and Tibetan. But part of this is to take a lot of ACIP encoding material that I have as well as available from AsianClassics.org and similar places.

I saw that JSkad had a conversion from ACIP to Unicode (text file). So I tried this, but the output didn't look like Unicode at all. I was using Notepad and Pages (latest), but both didn't show Tibetan Unicode fonts from the output, rather Roman letters with strange numbers.

Now, it could be an operator error, so I need to do something with the text file before using it, or something else.  In case someone has ideas what is happening and how to fix this, please post a comment. Also, if you have other tools or ideas how to convert ACIP encoding to Unicode on the Macintosh platform. If I get this working, a lot of really cool Tibetan material will be posted on dharmadictionary and similar places for public access.
