So how do I fix the "rm a*" program below now? (if there are some docs
somewhere explaining it, please just point me at them).


$ touch `printf "a1\243a"`
$ ls -b a*                
a1\243a
$ cat q.hs                

import Data.List
import System.Directory

main :: IO ()
main = do xs <- getDirectoryContents "."
          let ys = filter ("a" `isPrefixOf`) xs
          print ys
          mapM_ removeFile ys

$ ghc --make q
$ ./q 
["a1\61347a"]
q: a1�a: removeLink: does not exist (No such file or directory)
$ ls -b a*   
a1\243a
$ 


Thanks
