If you write it in the style of my earlier example and use

characters.
When printing to stdout it seems to skip any validation, but
writing to a file does give an exception:
```
auto inputStream = (args.length < 2 || args[1] == "-") ?
stdin : args[1].File;
auto outputFile = new File("output.txt");
foreach (line; inputStream.byLine(KeepTerminator.yes))
outputFile.write(line);
```
std.exception.ErrnoException@C:\D\dmd2\windows\bin\..\..\src\phobos\std\stdio.d(2877):
(No error)
According to the documentation, byLine can throw an UTFException
so relying on the fact that it doesn't in some cases doesn't seem
like a good idea.
