# Character types

| Data type      | Alias                             | Description                                                                                                                                                 |
| :------------- | :-------------------------------- | :---------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `CHAR(n)`      | `CHARACTER(n)`                    | Fixed size character string of size n. See [Database Limitations](/sql/appendices/database-limitations).                                                    |
| `VARCHAR[(n)]` | `CHARACTER VARYING [(n)]`, `TEXT` | variable-length with optional limit (n).<br /> If n isn’t specified, the maximum is used. See [Database Limitations](/sql/appendices/database-limitations). |

Notes

* Only ASCII characters are supported, 1 char = 1 byte.

* Character type literals should be surrounded by single quotes. Those must be the basic ASCII character 39 ('). Other variants, such as the left single-quote and right single-quote ASCII characters 145-146 (‘like this’), are not supported and would result in an error.
