Why Are My Persian Characters Garbled After Database Migration?

Decoding Character Encoding Issues in Database Storage

A puzzling situation arises when migrating an old website's data to a new script. The stored characters, originally rendered correctly by the old script, appear distorted in the new one. Upon investigation, it is discovered that the characters are stored in an unusual encoding.

The old script uses a database engine called TUBADBENGINE, which doesn't exhibit any peculiar characteristics. However, when data containing Persian characters is inserted using the old script, they are stored as strange-looking characters in the database.

On the other hand, when the data is entered directly into the database using SQL, the correct characters are preserved. However, attempting to retrieve this data using the new script results in garbled characters.

The culprit, as revealed in the answer, is the character encoding being used for the database connection. In this case, the database connection was set to latin1, which is an inappropriate choice for Persian characters. As a result, the characters were incorrectly converted when being stored in the database.

To resolve the issue, we need to convert the data in the database to the correct character encoding. One possible solution provided in the answer is:

SELECT CONVERT(BINARY CONVERT(field_name USING latin1) USING utf8) FROM table_name

This query can be used to retrieve the data using the correct character encoding. We can then use this result as an UPDATE statement to permanently correct the data in the database.

Once the data is properly encoded, the new script should be able to retrieve and display it correctly.
