Description	qualifier to indicate Unicode codepoint where property value for Han character (eg. stroke count) is applicable
Data type	String
Domain	instances of CJK Unified Ideographs (Q796156) or CJK Compatibility Ideographs (Q2493848)
Allowed values	4 character string that begin with 'F' or [3-9]; 5 character string that begins with '2'
Example 1	著 (Q54918611) (wikt:著) stroke count (P5205) → 11 applies to Unicode codepoint → 8457 (redundant) applies to jurisdiction (P1001) → Japan (Q17), mainland China (Q19188) applies to Unicode codepoint → 2F99F applies to jurisdiction (P1001) → Taiwan (Q865), North Korea (Q423)
Example 2	著 (Q54918611) (wikt:著) stroke count (P5205) → 12 applies to Unicode codepoint → 8457 (redundant) applies to jurisdiction (P1001) → Taiwan (Q865), Hong Kong (Q8646) applies to Unicode codepoint → FA5F applies to jurisdiction (P1001) → Japan (Q17)
Example 3	著 (Q54918611) (wikt:著) stroke count (P5205) → 13 applies to Unicode codepoint → 8457 (redundant) applies to jurisdiction (P1001) → South Korea (Q884)
Planned use	to be applied to Han character items with multiple Unicode codepoints

Motivation

An additional qualifier that is needed for CJKV characters with multiple codepoints. KevinUp (talk) 13:33, 23 July 2018 (UTC)

Discussion

•  Comment I think this qualifier should be only used for the codes of CJK Compatibility Ideographs (Q2493848) and CJK Compatibility Ideographs Supplement (Q2493862); i.e. in the above examples, "applies to Unicode codepoint → 8457" is redundant. That is because, from the point of view of those who use this data, this qualifier is used only when they specially want to get the data of specific CJK Compatibility Ideographs (Q2493848) or CJK Compatibility Ideographs Supplement (Q2493862). If an item has two or more codes of CJK Unified Ideographs (Q796156), it should be divided into more than one items. Also, applies to jurisdiction (P1001) data corresponding to CJK Compatibility Ideographs (Q2493848) or CJK Compatibility Ideographs Supplement (Q2493862) should be stored under the Unicode code point (P4213) statements of Han character items (ex.
  ⟨ 著 (Q54918611)    ⟩ Unicode code point (P4213) ⟨ 2F99F ⟩
  Unicode block (P5522) ⟨ CJK Compatibility Ideographs Supplement (Q2493862) ⟩
  applies to jurisdiction (P1001) ⟨ Taiwan (Q865)    ⟩
  applies to jurisdiction (P1001) ⟨ North Korea (Q423)    ⟩
  ), rather than repeatedly described in many places. --Okkn (talk) 18:02, 23 July 2018 (UTC)
•  Not done After careful perusal of the discussion above, I have decided that separate Han character items should be created for CJK Compatibility Ideographs (Q2493848) and CJK Compatibility Ideographs Supplement (Q2493862). Data related to those glyphs should be stored in separate items, eg. 著 (Q54918611) and 著 (U+FA5F) (Q55726748) to avoid further confusion. KevinUp (talk) 22:22, 23 July 2018 (UTC)
