Collations and character sets

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 if a character set or collation that you need is missing.
