This gist contains maps "not verifiable" GCCS characters documented in HKSCS-2004 Annex IV to Unihan or U-source records. The mapping for U-source characters should be mostly correct as their Adobe-CNS1 sources match the range of Adobe-CNS1-1, a supplement created for GCCS support.
This voluntary enrichment activity is followed by cake rewards. The mapping generated is released into public domain. For a more authoritive description of characters written in IDS, please refer to
