The following site lists Unicode characters by block and category,
shown either with fonts or with images. It also lists fonts that
support particular blocks.

http://www.fileformat.info/info/unicode

Plane 15 (0x0F0000-0xFFFFD) is private use area A, and plane 16
(0x100000-0x10FFFD) is private use area B. There's also a private use
area in the BMP at 0xE000-0xF8FF. The latter has been used for
fictional languages such as Klingon.
