2. Use std.parallelism for using multiple cores on the CPU
3. Use @fastmath of LDC

So a few easy things you can do:
1)
I think you have to decode your input to UTF-8.
stdin
.byLineCopy(No.keepTerminator)
.each!((string file_name_raw) {
// change Latin1String to the code page of your console;
// use the 'chcp' command to see the current code page of
your console

import std.encoding;

Works for me. I created a file with the name "中文.txt" and

It's unclear what your problem is but here a wild guess.
Windows API's for Unicode use UTF-16 as far as I know.
