Why do I get a MalformedInputException from this code?

Question

I'm a newbie in Scala, and I wanted to write some sourcecodes from myself for me to get better. I've written a simple object (with a main entry) in order to simulate a "grep" call on all files of the current directory. (I launch the program from Eclipse Indigo, and in Debian Squeeze) : ``` package com.gmail.bernabe.laurent.scala.tests import java.io.File import scala.io.Source object DealWithFiles { def main(args:Array[String]){ for (result <- grepFilesHere(".*aur.*")) println(result) } private def grepFilesHere(pattern:String):Array[String] = { val filesHere = new File(".").listFiles def linesOfFile(file:File) = Source.fromFile(file).getLines.toList for (file <- filesHere; if file.isFile ) yield linesOfFile(file)(0) } } ``` But I get a java.nio.charset.MalformedInputException, which I am not able to solve : ``` Exception in thread "main" java.nio.charset.MalformedInputException: Input length = 1 at java.nio.charset.CoderResult.throwException(CoderResult.java:260) at sun.nio.cs.Stream…

Accepted Answer

From the JavaDoc:

MalformedInputException thrown when an input byte sequence is not legal for given charset, or an input character sequence is not a legal sixteen-bit Unicode sequence.

Pass the currect encoding as parameter to `Source.fromFile` method.
