What fonts to browse scala source code and render <- and =>

I'm using Eclipse on Windows 7 to browse Scala source code. Scala allows ⇒ to be used instead of =>, and ← instead of <-.

However, I can't seem to find a good clear monospace font that renders the unicode ⇒ and ← well. Often I just get a box instead of ⇒.

I've tried: Consolas - is the clearest general font, but won't render ⇒ Anonymous Pro - doesn't render ⇒ Deja Vu Sans Mono - does render ⇒, but it is so small it is hard to see!

For my own code, I can just avoid ⇒, but this doesn't help viewing third party library source. How have other folks solved this problem? If other folks are using ⇒ in their code then presumably they also know of a monospace font that also renders it clearly :-)
