This ideograph is a disunification of U+7DF4 練 that also affects U+FAB0 練. If accepted, the kIRG_KPSource property value of U+FAB0, KP1-671B, should be moved to the new code point, and the kIRG_KPSource property value of U+FAB0 should be changed to KPU-0FAB0. As with the most recent disunification, Japan will not want to move the kIRG_JSource property value of U+7DF4, J0-4E7D, to the new code point due to compatibility concerns.

Note that disunifications have been processed via previous IRG working sets, which is why the UTC decided to submit this ideograph. UTC-01159, UTC-01162, and UTC-02972 in IRG Working Set 2017 served as precedents.

I don't understand how encoding this character affects FAB0 which is presumably a variant form of 7DF4 used in DPRK, and is not a transcription of a bronze script character as shown by the only evidence provided for the new character. Also, can we move the KP source reference without agreement from DPRK experts? In all the evidence for disunification seems very weak to me.

Per the details in document IRG N2785, the UTC formally withdraws the withdraw of this ideograph, and requests that it be added back to the M Set.
