| identifiers | Double quotes; backslash escapes (a newline inside a string... | — |
| row limit | — | (driver dependent) |
| dates | No date type: dates arrive as strings | Date (D) |
| long text | — | Memo (M) |
| binary | Not supported natively - base64 inside a string | — |
| separator | Newline between records | — |
| encoding | UTF-8 by definition | — |
