Repairing Corrupted UTF-8 Encoding

Encountering broken UTF-8 encodings can be a frustrating challenge, especially when dealing with databases and web applications. This guide will delve into a potential solution for fixing damaged UTF-8 characters, particularly those represented as î and similar sequences.

The solution involves utilizing PHP 5 and MySQL along with the following key configurations:

• Database collation set to utf8_general_ci
• PHP utilizing a proper UTF-8 header
• Notepad configured for UTF-8 without BOM
• phpMyAdmin managing database administration

While certain accented characters may remain unaffected, this technique will address the problematic î, í, ü, and their counterparts.

To restore the integrity of your UTF-8 characters, adopt the given approach:

MySQL Data Dump and Restoration

1. Perform a data dump of your database using the following command:

mysqldump -h DB_HOST -u DB_USER -p DB_PASSWORD --opt --quote-names \
    --skip-set-charset --default-character-set=latin1 DB_NAME > DB_NAME-dump.sql

2. Reload the data into your database using this command:

mysql -h DB_HOST -u DB_USER -p DB_PASSWORD \
    --default-character-set=utf8 DB_NAME < DB_NAME-dump.sql

By following these steps, you should effectively repair any corrupted UTF-8 encodings within your database, ensuring proper display of accented characters.
