--- title: "Collations and character sets" description: Supported charsets and collations. --- Dolt supports a subset of the character sets and collations that MySQL supports. Notably, the default character set is `utf8mb4`, while the default collation is `utf8mb4_0900_bin` (a case-sensitive collation). This default was chosen as it has the fastest implementation, and also from a legacy perspective, as before proper collation support was added, it was the only real collation that we supported. This differs from a standard MySQL instance, which defaults to `utf8mb4_0900_ai_ci` (a case-insensitive collation). Character sets and collations are added upon request, so please [file an issue](https://github.com/dolthub/dolt/issues) if a character set or collation that you need is missing. **Currently supporting 181 of 286 MySQL collations.** | Collation | Character Set | Supported | |:----------------------------|:--------------|:----------| | armscii8_bin | armscii8 | ❌ | | armscii8_general_ci | armscii8 |
