While working on https://github.com/nurpax/sqlite-simple there have been occasions when I've tried to decide whether to use ByteStrings or Text strings. I note that postgresql-simple and mysql-simple use ByteStrings exclusively in the API. Has a convention formed in the Haskell community on which strings should be used in APIs that pass strings around? In my case, blobs will anyway be passed around as ByteStrings. But SQLite's C strings are UTF8 and some might prefer to Text over ByteStrings. Or support both in the API? This matters in the low-level bindings too, where result accessors need to return either ByteStrings or Text objects for TEXT fields. Currently direct-sqlite uses the String type but Irene is thinking of changing the type to a more efficient representation (https://github.com/IreneKnapp/direct-sqlite/issues/3). Sqlite-simple links against both bytestring and text already, so from a purely package dependency point of view the choice doesn't really matter. But sqlite-direct will need to choose one or the other for its string type in the SQLText s constructor. Any thoughts? Cheers, Janne
