How to resolve java.nio.charset.UnmappableCharacterException in Scala 2.8.0?
- by Roman Kagan
I'm using Scala 2.8.0 and trying to read pipe delimited file like in code snipped below:
object Main {
def main(args: Array[String]) :Unit = {
if (args.length > 0) {
val lines = scala.io.Source.fromPath("QUICK!LRU-2009-11-15.psv")
for (line <-lines)
print(line)
}
}
}
Here's the error:
Exception in thread "main" java.nio.charset.UnmappableCharacterException: Input length = 1
