"a" and "A" are identical, according to utf8_unicode_ci and utf8_general_ci, but not
utf8_bin.
That is, I would not expect "[" to slip in between them.
About 80% of the way down this page, there is a list of some of the 'equivalences' in
selected collations:
http://mysql.rjweb.org/doc.php/charcoll
In particular:
utf8 : utf8_unicode_ci
A=a=ª=À=Á=Â=Ã=Ä=Å=à=á=â=ã=ä=å
ae az Æ=æ
says that lots of things collate equal to 'A'. All of them sort before ae > az >
the ligature Æ (upper or lower case)
