Too long for a comment. Check also all other character set definitions.
default charset variables
SHOW VARIABLES LIKE 'character_set%';
show default data encoding
Databases:
SELECT SCHEMA_NAME, DEFAULT_CHARACTER_SET_NAME, DEFAULT_COLLATION_NAME FROM information_schema.SCHEMATA;
Tables:
SELECT TABLE_SCHEMA, TABLE_NAME, ENGINE, TABLE_COLLATION FROM TABLES LIMIT 1000;
Columns:
SELECT COLUMN_NAME, TABLE_NAME, CHARACTER_SET_NAME, COLLATION_NAME FROM information_schema.COLUMNS WHERE CHARACTER_SET_NAME IS NOT NULL LIMIT 1000;
I added a limit statement to only show the first 1000 rows. Adapt for example with: WHERE CHARACTER_SET_NAME = '#610'
To show all abailable charsets:
SHOW CHARACTER SET;
Hope that helps finding the problem.
