Great suggestions so far--I have just one thing to add.

If you ever reach the point at which you find yourself examining code tables to figure out what character set something is using, you might also want to find a good hex editor so that you can examine your data byte by byte. Since what you're looking at otherwise is always going to be the data as interpreted by a particular program (email program, web browser, text editor), looking at it with a hex editor can give you a nice grounding in reality, without that extra layer of interpretation.
