This might be interesting, because you find a lot of font-information in there:

As far as I remember there is a free 30-days-trial period.

And of course there is Adobe's ATM Light:

FontLister lets you view all of your fonts, edit the sample text that each font is displayed in, get a close up of the font's character sets etc.
Its quick and easy to use.

Version 2 is free from:

Version 3 is free to download, but $5 to use for more than 30 days - it doesn't stop working or become limited in features after 30 days, which is even more reason to cough up the miniscule fee!

(I've had version 3 for ages, and thought it was freeware until I went to the Help screen to get the details for this post, so I'm just off to pay for it now).

Software for the cost of a pint and a packet of crisps - you just have to support it really.

I just noticed that the same website also has a freeware program called FontSelector, which lets you browse and print all your installed fonts. (FontLister gives more info and works with any fonts on the system, installed or not).
