Create mediawiki having few files
Go to Special:ListFiles
If search input box type some text from middle of name of some file or from beginning
e.g. if there is "My autumn file.txt" type "autumn"
Result: after pressing button file does not appear in list
MW: 1.35.1
Probale cause: ImageListPager makes some case changes then use LOWER function to do case-insensitive compare.
But img_name is varbinary so case does not change and even LIKE search is case-sensitive.
Proposed fix: convert varbinary to utf8mb4 before calling LOWER, also other php function is needed.
