What are the potential security implications of changing collations?

While changing collations can resolve error 1033, be aware of potential security implications. Different collations sort and compare strings differently. Incorrectly chosen collations can lead to vulnerabilities, particularly in areas like authentication or authorization if string comparisons are used for these purposes. Always choose a collation appropriate for your data and security requirements. `utf8mb4_unicode_ci` is generally a safe and widely compatible choice.
