Description

Hello. I use like with lowercaseString and Russian symbols but LOWER doesn't convert them to lowercase in the query. I tried to create my own function but it didn't work for me. How to solve this problem? Thanks.

// in name value: ПРИВЕТ from database let search_name = "Привет" user.filter(name.lowercaseString.like("%" + search_name.lowercased() + "%"))

Contributor guide

Research direction
Check if the SQLite database is compiled with ICU support. The LOWER function may not handle non ASCII characters without ICU. Consider using SQLite's LIKE with a case insensitive collation or enabling ICU extension.
