Bug#55980 Character sets: supplementary character _bin ordering is wrong
Problem:
- ORDER BY for utf8mb4_bin, utf16_bin and utf32_bin returned
results in a wrong order, because old functions
(supporting only BMP range) were used to handle these collations.
- Additionally, utf16_bin did not sort supplementary characters
between U+D700 and U+E000, as WL#1213 specification specified.
include/m_ctype.h:
Adding prototypes.
mysql-test/include/ctype_filesort2.inc:
Adding a new shared test file.
mysql-test/t/ctype_utf8mb4.test:
Adding tests.
strings/ctype-ucs2.c:
- Fixing my_strncoll[sp]_utf16_bin to compare
binary representation instead of code points,
to make columns with indexes sort correct.
- Fixing my_collation_handler_utf32_bin and
my_collation_handler_utf16_bin to use new
functions.
strings/ctype-utf8.c:
- Adding my_strnxfrm[len]_unicode_fill_bin()
to handle utf8mb4_bin, utf16_bin and utf32_bin,
using 3 bytes per weight.
This function also performs special reordering in case of utf16_bin.
- Fixing my_collation_utf8mb4_bin handler to use the
new function.
