Invalid utf8 character string on mysqldump script

I've created a copy of a database and changed the collation and charset to utf8mb4 (originally it was latin1), then used mysqldump to create a script for a Flyway database migration.

When I run the following script

-- MySQL dump 10.13  Distrib 5.5.62, for Win64 (AMD64)
--
-- Host: localhost    Database: feedback
-- ------------------------------------------------------
-- Server version   8.0.15

flyway shows messages like these:

WARNING: DB: Invalid utf8 character string: 'C7C34F' (SQL State: HY000 - Error Code: 1300)
WARNING: DB: Incorrect string value: '\xC3O FUN...' for column 'claimed_name_pt' at row 10 (SQL State: HY000 - Error Code: 1366)

When I run the dump script using tools like SQLyog and MySQL Workbench the data is correctly inserted, so how can I fix that for Flyway?

Solution

  • Found the missing part to fix the migration issue. I had to add encoding settings to the Flyway's connection string:

    FLYWAY_URL="jdbc:mysql://${db_instance.default.address}:3306/${mysql_database.db-app.name}?characterEncoding=UTF-8&useUnicode=true"
