What is the best way to convert a String to a ByteString in Haskell?
My gut reaction to the problem is
import qualified Data.ByteString as B
import Data.Char (ord)
packStr = B.pack . map (fromIntegral . ord)
But this doesn't seem satisfactory.

A:
Data.ByteString[.Lazy].Char8.pack
You can typically use hoogle to find functions.

A:
Data.ByteString.UTF8.fromString is also useful. The Char8 version will lose the unicode-ness and UTF8 will make a UTF8-encoded ByteString. You have to choose one or the other.

In case the question comes up: this function is not located by Hoogle because it only indexes a small set of libraries (those shipped with GHC). Expanding the set of libraries indexed by Hoogle has came up several times but hasn't been done I think due to time constraints of the Hoogle developer (Neil).FYI, the function discussed here is from the utf8-string package.

@peaker: Not to my satisfaction. Hayoo does a poor job at type search, particularly when the type is general or polymorphic.
