If you are sending emails using utf8 data, you might want to also convert your emails to send in UTF8. I had a situation where certain characters "broke" in emails even though they were stored as UTF-8 in the database. Éleanore and Eleanore might be considered the same in some collations. Make sure to choose the right collation, or you might get unique key conflicts. Here is an example: ALTER TABLE t1 CHANGE c1 c1 BLOB ĪLTER TABLE t1 CHANGE c1 c1 VARCHAR(100) CHARACTER SET utf8 Then to a nonbinary column with the desired character set.
Set, you can convert the column to use a binary data type first, and If the contents are encoded in a different character If the column has a nonbinary data type (CHAR, VARCHAR, TEXT), itsĬontents should be encoded in the column character set, not some otherĬharacter set. In case the data is not in the same character set you might consider this snippet from (like following) ALTER TABLE rma CHARACTER SET utf8 COLLATE utf8_general_ci ALTER TABLE rma CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci ĪLTER TABLE rma_history CHARACTER SET utf8 COLLATE utf8_general_ci ALTER TABLE rma_history CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci ĪLTER TABLE rma_products CHARACTER SET utf8 COLLATE utf8_general_ci ALTER TABLE rma_products CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci ĪLTER TABLE rma_report_period CHARACTER SET utf8 COLLATE utf8_general_ci ALTER TABLE rma_report_period CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci ĪLTER TABLE rma_reservation CHARACTER SET utf8 COLLATE utf8_general_ci ALTER TABLE rma_reservation CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci ĪLTER TABLE rma_supplier_return CHARACTER SET utf8 COLLATE utf8_general_ci ALTER TABLE rma_supplier_return CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci ĪLTER TABLE rma_supplier_return_history CHARACTER SET utf8 COLLATE utf8_general_ci ALTER TABLE rma_supplier_return_history CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci ĪLTER TABLE rma_supplier_return_product CHARACTER SET utf8 COLLATE utf8_general_ci ALTER TABLE rma_supplier_return_product CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci WHERE C.collation_name = T.table_collationĪND T.table_schema = 'your_database_name'Īdjusting table columns' collation and character setĬapture upper sql output and run it.
