    Description

      The collation defined in the attached Index.xml does not work.
      It crashes in DEBUG build and writes "Expansion too long" error to server error log in release build.

      I seems the problem happens because MariaDB collation customization currently has some limitation in shifting characters which have implicit weights (i.e. those not listed on DUCET).
