Name some good dictionary fonts!

I might be getting involved in a project that involves making a dictionary for a First Nations/Native North American language, and I'd appreciate it if someone could suggest some fonts. The materials are currently mostly in Gentium, which looks okay to me. Although its coverage is impressive and it doesn't look half bad, I have the knee-jerk reaction to free fonts that many of us have - it's not a reasonable reaction, I think, in this case. SIL as an organization is radically different from 1001FreeFonts.com, so I'm not worried about malformed fonts causing issues at print. I'm simply curious if there isn't anything out there that I've never heard of due to the fact that I've spent the last decade in a cash-strapped nonprofit organization.

The glyph complement I'd need is already covered by Gentium. It features some IPA here and there, and quite a few characgters that I've never seen in use before. Some of the necessary glyphs include:

  Latin letter L with "belt." (What? Belt? Well, I never.)

  Glottal stop glyph

  Small capital I

  Modifier letter half triangular colon (Once again, what?)

That's just skimming off the top. Any suggestions?
