[dm-l] Mac help

Hi all,

I have a new research assistant who is going to be helping us at the DM journal. She's a Mac user, and to get her set up, I'd appreciate any advice this list has for software for the following:

1) SVN client (we use subversion for our journal back end and she'll need access; I'm assuming the Mac Version of Oxygen comes with the same SVN client the other versions do, but it might be nice to have a separate svn client as well--something like turtleSVN for Windows.

2) Unicode navigator--is there a standard code point navigator for Mac? Almost right away we're going to have her putting in some greek and mathematical symbols in an article: is there a utility for browsing and search code points?
