Unicode wants to be able to preserve round-trip re-encoding from this other standard which has separate letter-K and degree-K characters. Making these small sacrifices for compatibility is how Unicode became the defacto world standard.
- shiomiru 10mo agoThe "other standard" in this case being IBM-944. (At least looking at https://www.unicode.org/versions/Unicode1.0.0/ch06.pdf https://www.unicode.org/versions/Unicode1.0.0/ch06.pdf p. 574 (=110 in the PDF) I only see a mapping from U+212A to that one.)

- shiomiru 10mo agoThat "deeper explanation" seems incorrect, considering that the KSC column is empty in the mapping linked above.
- kahirsch 10mo agoThe ICU mappings files have entries for U212A in the following files: gb18030.ucm ibm-1364_P110-2007.ucm ibm-1390_P110-2003.ucm ibm-1399_P110-2003.ucm ibm-16684_P110-2003.ucm ibm-933_P110-1995.ucm ibm-949_P110-1999.ucm ibm-949_P11A-1999.ucm
