Why won't any faces show up in the UV Image Editor? When I unwrap the character I designed, I get only a few faces visible in the UV image editor, although all the faces are selected in the 3d viewport in edit mode.

Those faces are probably the one I added to "close" the character's head (for some reason I had a hole that I closed adding faces one by one and then checked to remove doubles). Maybe it's a coincidence. 

And there is more: If I use 'circle select' (C + left-click) over "empties" area in the UV image editor (not in island mode), I can see that faces get activated in the 3d viewport (edit mode)! Of course, I have restarted Blender to see if the problem persists and it does.

All this weird behavior happens before I create an image. Once I create a new image or use an existing one as a UV, the meshes in the UV Image editor don't show up at all! 

When I do all this process with the monkey figure I have no problem.

Could you have a look to my blend file and tell me what's wrong?

You have 'UV Local View' turned on in the image editor. Go to the image editor and then View> UV Local View to turn it off:



I'm don't fully understand this feature but it seems to be mostly used for Blender Internal and not Cycles. There is a small discussion about it here:
