Storing iOS5 Emojis in MySQL
Issue:
iOS5 emojis, represented by 4-byte codes, are not being stored correctly in MySQL 5.5.10. While the character set is set to utf8mb4, the emojis appear as '???' in the database.
Solution:
To store iOS5 emojis in MySQL, ensure the following:
-
Database Configuration:
- Verify that the database character set (character_set_database) is set to utf8mb4.
- Convert all tables' default character sets and text fields to utf8mb4.
-
Application Configuration:
- Set the database connection's character set to utf8mb4 in the application code.
- Update the mysql client library in the application if it does not support utf8mb4.
-
Data Viewing:
- When viewing the data through the mysql client, use SET NAMES utf8mb4 to display emoji correctly. Ensure the viewing machine can support emoji.
-
Compatibility:
- Note that 4-byte Unicode characters may not be fully supported by all components. Check that all levels of the application can handle these characters without corruption.
Once these steps are complete, MySQL should be able to store iOS5 emojis accurately.

MySQL: String Data Types and CollationsMay 09, 2025 am 12:08 AMThe string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.
