+??	The conversion table for character set XX does not match with

+{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
+    -0xA1AA 0x2014
+    -0xA844 0x2015
+
+  In addition the Unicode tables contain mappings for the GBK characters
+  0xA8BC, 0xA8BF, 0xA989 to 0xA995, and 0xFE50 to 0xFEA0.
