Hi Ivan, thanks for the tip, but how do I use the library? I can't really make out how to feed it UTF-16 and get String (UTF-8) back. Günther BTW: I need this function because I'm using HDBC-ODBC with MS Access and in MS Access apparently every string is in UTF-16. Am 28.01.10 12:47, schrieb Ivan Lazar Miljenovic:

is there a library which converts from utf-16 to utf-8?

The text library can (you can also choose between big and little endian UTF-16).

Haskell String type isn't UTF-8 encoded. it's [Char] where Char is in UCS-4 aka UTF-32 :)

That's not quite correct. [Char] is a sequence of Unicode code points, UTF-32 is one possible encoding of those code points. The difference is similar to the one between an integer an e.g. its string representation. Cheers, Johan

One way (probably not very efficient): import Data.Text.Encoding convert :: Bytestring -> Bytestring convert = encodeUtf8 . decodeUtf16LE No claims are made about efficiency of this technique (mainly because unless you're already using Bytestrings, then it probably isn't very efficient). -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
