The normative kIRG_KPSource (aka KP-source) property, which is documented in UAX #38, Unicode Han Database (Unihan), was introduced in Unicode Version 3.1.1 (2001), and its property values have changed in subsequent versions of the Unicode Standard. The purpose of this Unicode Technical Note is to document the history of changes to this property whose property values correspond to the DPRK character set standards, KPS 9566 and KPS 10721. No one outside of DPRK has ever seen the actual KPS standards, so it is useful to document property value changes that have been made to this property. The KPS 9566 character set standard, whose kIRG_KPSource source prefix is KP0, can be glimpsed through ISO-IR-202:1998 (PDF).

The body of this Unicode Technical Note is contained in the single-sheet Excel file “tn50-2.xlsx.”
The Excel file covers a total of 210 code points, one per row and in increasing code-point order, with property values in columns ranging from Unicode Version 3.1.1 (2001) to 15.1.0 (2023). For cases when a particular version of the Unicode Standard exhibited no changes to the kIRG_KPSource property, a range of version numbers is specified for that column. 53 of the code points correspond to CJK Unified Ideographs in the CJK Unified Ideographs (5), Extension A (5), Extension B (34), Extension C (8), and Extension G (1) blocks, and the remaining 157 code points, which are highlighted in blue, correspond to CJK Compatibility Ideographs in the CJK Compatibility Ideographs (107) and CJK Compatibility Ideographs Supplement (50) blocks. Significant changes are highlighted in red and green. Red signifies a property value that was removed from the code point in subsequent versions of the Unicode Standard. Green signifies either the new code point for a removed property value or its replacement property value in the case of disunification.
