-- Step 2 of the UTF-8 Multibyte (utf8mb4) conversion for MySQL
--
-- Enlarge some database columns to avoid data losses, then convert all tables
-- to utf8mb4 or utf8, then set default character sets and collations for all
-- tables, then add back indexes previosly dropped with step 1,
-- utf8mb4-conversion-01.sql, but add them back with limited lenghts of
-- columns.
--
-- Do not rename this file or any other of the utf8mb4-conversion-*.sql
-- files unless you want to change PHP code, too.
--
-- IMPORTANT: When adding an index modification to this file for limiting the
-- length by which one or more columns go into that index,
--
-- 1. remember to add the statement to drop the index to the file for step 1,
--    utf8mb4-conversion-01.sql, and
--
-- 2. check if the index is created created or modified in some old schema
--    update sql in an "ALTER TABLE" statement and limit the column length
--    there, too ("CREATE TABLE" is ok, no need to modify those).
--
-- This file here will the be processed with reporting exceptions, in opposite
-- to the file for step 1.
--

--
-- Step 2.1: Enlarge columns to avoid data loss on later conversion to utf8mb4
