{UD} I don't doubt for a minute that some of the conversion tables contain

errors. We tried the best we can and relied on automatic generation of the

data to prevent human-introduced errors but this still is no guarantee. If

you think you found a problem please send a bug report describing it and

give an authoritive reference. The latter is important since otherwise

the current behaviour is as good as the proposed one.

Before doing this look through the list of known problem first:

- the GBK (simplified Chinese) encoding is based on Unicode tables. This
|

is good. These tables, however, differ slightly from the tables used
|

by the M$ people. The differences are these [+ Unicode, - M$]:

+0xA1AA 0x2015

+0xA844 0x2014

|

In addition the Unicode tables contain mappings for the GBK characters
|

0xA8BC, 0xA8BF, 0xA989 to 0xA995, and 0xFE50 to 0xFEA0.
