Raleway is an elegant sans-serif typeface, designed in a single thin weight. It is a display face that features both old style and lining numerals, as well as a stylistic alternate inspired by more geometric sans-serif typefaces than it’s neo-grotesque inspired default character set.
This website has a huge collection of fonts which are all free to download. I have downloaded a bunch and they all work great, and seem to have all the special characters included as well.
The only problem I have with this site is restraining myself from downloading hundreds of new fonts, which I will probably never use. Of particular interest to me was the Blackletter Revival collection. I started looking at these typefaces when I was designing our wedding invitations, and I think they are beautiful.
Go get yourself some new fonts but don’t go crazy; you know you’ll never use them all.
