          Issue ID: 23588
           Summary: Std lacks a way to read Unicode from a file expect by
                    line
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1

```
struct filebydchar{
        dstring me; alias me this;
        this(string s){
                import std.file;
                import std.conv;
                me=readText(s).to!dstring;
        }
        int i;
        dchar front(){
                return me[i];
        }
        void popFront(){
                i++;
        }
        bool empty(){
                return i>=me.length;
        }
}
```

I would expect a `std.File.byDChar` rather then what may be poor attempts at implementing unicode logic on some c interface
