Re: String != [Char]

If the input is specified to be UTF-8, wouldn't it be better to call the method unpackUTF8 or something like that? On Mon, Mar 19, 2012 at 12:59 PM, Johan Tibell wrote:

I've been thinking about this question as well. How about

class IsString s where unpackCString :: Ptr Word8 -> CSize -> s

What's the Ptr Word8 supposed to contain? A UTF-8 encoded string?

Yes.

We could make a distinction between byte and Unicode literals and have:

class IsBytes a where unpackBytes :: Ptr Word8 -> Int -> a

class IsText a where unpackText :: Ptr Word8 -> Int -> a

In the latter the caller guarantees that the passed in pointer points to wellformed UTF-8 data.
