patch 9.1.1640: Unicode has deprecated some code-points
Problem: Unicode has deprecated some code-points
Solution: Update the digraph tables to align with the Unicode v16
release (David Friant)
This commit updates the digraphs Left-Pointing Angle Bracket '</'
and Right-Pointing Angle Bracket '/>' to account for the fact that
the old Unicode codepoints for them (2329 and 232A, respectively)
have been deprecated. As per the Miscellaneous Technical code chart
(https://www.unicode.org/charts/PDF/U2300.pdf), the old digraphs
have been reassigned to the CJK Left Angle Bracket and Right Angle
Bracket (3008 and 3009) with their declaration moved to the
appropriate block.
This commit also introduces the new digraphs '<[' and ']>' to
represent the Mathematical Left Angle Bracket and Mathematical
Right Angle Bracket (27E8 and 27E9) to replace the deprecated code
points in the Technical block.
Tests have been added and, I believe, the documentation has been
updated accordingly.
