How Can I Convert Latin1 Data to UTF-8 in a MySQL UTF-8 Table?

Converting Latin1 Characters to UTF8 in a UTF8 Table

In PHP scripts, it is important to set the character encoding to UTF-8 to ensure proper handling of diacritics and special characters. When working with tables that were originally created with Latin1 collation, it becomes necessary to convert the existing data to UTF-8.

To tackle this issue, one can use the convert function in MySQL. The following query demonstrates this approach:

UPDATE `table` SET `name` = convert(cast(convert(`name` using latin1) as binary) using utf8)
WHERE `name` IS NOT NULL;

This query converts the name column, which contains Latin1-encoded data, to UTF-8. The inner conversion from binary to string is necessary to ensure proper handling of the Latin1 data.

It is worth noting that, depending on how the data was affected during the encoding conversion, the inner conversion may not be necessary. Experimentation may be required to determine the optimal solution for a particular table.

By implementing this conversion process, the Latin1 characters in the UTF8 table can be successfully corrected, allowing for proper display and manipulation of diacritics and special characters.
