Since last week's deployment of MBS-10416, invalid characters can no longer be entered. It's time to remove invalid characters from existing characters. These can be found in the database using the following query adapted from remove_invalid_characters subroutine:

SELECT *
FROM annotation
WHERE text ~ '[\x0-\x8\xB-\xC\xE-\x1F\xD800-\xDFFF\xFDD0-\xFDEF\xFEFF\xFFFE-\xFFFF\x1FFFE-\x1FFFF\x2FFFE-\x2FFFF\x3FFFE-\x3FFFF\x4FFFE-\x4FFFF\x5FFFE-\x5FFFF\x6FFFE-\x6FFFF\x7FFFE-\x7FFFF\x8FFFE-\x8FFFF\x9FFFE-\x9FFFF\xAFFFE-\xAFFFF\xBFFFE-\xBFFFF\xCFFFE-\xCFFFF\xDFFFE-\xDFFFF\xEFFFE-\xEFFFF\xF0000-\xFFFFF\x100000-\x10FFFF]';

There are 139 characters to be removed:

Attached is a dump of annotations where invalid characters have been replace with their codepoint in the form U+{HEXA}.
