Can you show the program you are using that throws when using
byLine?
Here's a version that only outputs the first chunk:
```
import std.stdio;
import std.range;
import std.algorithm;
import std.file;
import std.exception;
void main(string[] args) {
enforce(args.length == 2, "Pass one filename as argument");
auto lineChunks = File(args[1],
"r").byLine.drop(4).chunks(10_000_000/10);
new File("output.txt", "w").write(lineChunks.front.joiner);
}
```
If you write it in the style of my earlier example and use
counters and if-tests it will work. byLine by itself won't try to
interpret the characters (won't auto-decode them), so it won't
trigger an exception if there are invalid utf-8 characters.
