GBK is defined in an annex to GB 13000 (essentially the PRC
Translation of Unicode 1.1) in order to bring GB 2312:80 inline with
the rest of the ideographs in the I block of Unicode. As others have
mentioned, this is also the character set adopted by Microsoft for
CP936.
Ken Lunde's "CJKV Information Processing" has a good description of
the evolution and interrelationships between the GB standards.
As far as mapping tables go, the best one you'll find is the Microsoft
or ICU mapping tables. I personally have not seen an official mapping
table from GB 13000. As others have noted, Microsoft has extended the
"pure" GBK with Euro, and perhaps other code points.
GB 2312:80 is a proper subset of GBK, so you can map EUC-CN encoded
text to Unicode using a GBK mapping table. Be aware, though, that
going the other direction can be problematical: GBK can contains code
points that do not exist within GB 2312:80, so you need to be careful
going the other direction.
