Can I just tell dmd that I'm reading a Latin1 or ISO 8859-1 
file?
I've messed with the std.encoding module but really can't 
figure out what I need to do.

There must be a simple solution to this.

This seems to work:


import std.stdio, std.file, std.encoding;

void main()
{
    auto latin = cast(Latin1String) read("/tmp/hi.8859");
    string s;
    transcode(latin, s);
    writeln(s);
}

I thought I was in good shape with your above suggestion.  I does 
help me read and process text.  But when I go to print it out I 
have problems.

Here is my input file:
°F

Here is my code:
import std.stdio;
import std.string;
import std.file;
import std.encoding;

// Main function
void main(){
    auto fout = File("out.txt","w");
    auto latinS = cast(Latin1String) read("in.txt");
    string uniS;
    transcode(latinS, uniS);
    foreach(line; uniS.splitLines()){
       transcode(line, latinS);
       fout.writeln(line);
       fout.writeln(latinS);
    }
}

Here is the output:
°F
[cast(immutable(Latin1Char))176, cast(immutable(Latin1Char))70]

If I print the Unicode string I get an extra weird character.  If 
I print the Unicode string retranslated to Latin1, it get weird 
pseudo-code.
Can you help?
