Re: std.file and non-English filename in Windows
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;
auto raw = cast(immutable( Latin1String)[]) file_name_raw;
string file_name_utf8;
transcode(raw, file_name_utf8);
writefln("%s --> %s", file_name_utf8, file_name_utf8.exists);
});

Works for me. I created a file with the name "中文.txt" and
std.file.exists returned true.
Is your D source file saved in ASCII by any chance? Try saving
it with a different encoding, such as UTF8.
Yes, "中文.txt".exists return true. But when then filename read
from stdin,
it return false
stdin
.byLineCopy(No.keepTerminator)
.each!((a) { writefln("%s --> %s", a, a.exists); });
dir *.txt /b | test.exe
English.txt --> true
中文.txt --> false
Problem solved! I change the properties of cmd from "Raster
Fonts" to "Consolas" and all work well. But I don't know why.

I would not have expected a Unicode bug like this to be in std.file, but it's certainly possible. It's also possible that the console needs to be set to UTF-8 or UTF-16 or something, since the default often seems to cause problems for folks - though unless the file names are coming from the command-line, I wouldn't have expected that to be an issue. I do almost nothing with Windows though, so I'm not very familiar with the ins and outs of that mess. - Jonathan M Davis

In Windows, exists, rename, copy will report file not exists when you input non-English filename, such as Chinese 中文.txt
