hGetContents bug?

If I open a file using "openFile" from the IO module (x <- openFile "foo.txt" ReadMode) and convert it to a String via hGetContents (y <- hGetContents x) and finally try to print the file on the screen (putStrLn y) I'll get a strange result if the file contains the character 1A-hexadecimal (or 26-decimal): all characters beyond this point won't be printed on the screen. If I use openFileEx (from IOExts module) rather than openFile, some characters will be printed after the 1A/26, but not all of them. I know this special character is related to EOF or something like that in Windows platforms, but is this the expected behavior of function hGetContents? (please reply to both the list AND me) Thanks, -- Andre Furtado
