Don't know if anyone attended or was monitoring UTC Meeting #178 but a change
was made to idna2008derived files U+19DA status of PVALID to DISALLOWED:
https://www.unicode.org/L2/L2024/24006.htm#178-N4
Section 7.1) U+19DA inconsistent IDNA2008 status
[178-N4] Note:
The idna2008derived files for versions 7.0 to 15.1 (inclusive) had U+19DA as
PVALID which was in conflict with its IdnaMappingTable.txt IDNA2008 Status of XV8.
The idna2008derived files have been corrected with 19DA as DISALLOWED.
