Description G. Halkes 2012-12-30 17:15:33 UTC
The Big5-HKSCS character set converter incorrectly maps U+23FF0 to the sequence 8E6A and U+25D20 to FDD8. This was a bug in the Unihan database up until Unicode version 4.0.1, which switched the mappings. Thus U+23FF0 should map to FDD8 and U+25D20 should map to 8E6A.

From the 4.0.1 version of the Unihan database:
U+23FF0 kHKSCS  FDD8
U+25D20 kHKSCS  8E6A

The 3.2.0 version still has:
U+23FF0 kHKSCS  8E6A
U+25D20 kHKSCS  FDD8
