I'm new to dlang. I didn't find much tutorials on internet about how to read/write Chinese easily. std.encoding doesn't seem to support GBK or GB18030:

"Encodings currently supported are UTF-8, UTF-16, UTF-32, ASCII, ISO-8859-1 (also known as LATIN-1), ISO-8859-2 (LATIN-2), WINDOWS-1250, WINDOWS-1251 and WINDOWS-1252."

Then what is best way to read GBK/GB18030 contents ? Even GBK/GB18030 file names ?

It appears that encoding is not supported.

There is a scant mention of it, in the BOM detection. But I don't think there's any mechanism to encode/decode it.

D has direct bindings to C, so possibly using a C library. I don't see anything jumping out at me from code.dlang.org

There is mention of unicode/GBK conversion, maybe it could be helpful

Thanks for quick answers. Now I found I can read both UTF8 and UTF-16LE
chinese file:
string txt = std.file.read(chineseFile).to!string;

and write to UTF8 file:
std.file.write(utf8ChineseFile, txt);

But still need figure out how to read/write GBK directly.

module chinese;
import std.stdio : writeln;
import std.conv;
import std.windows.charset;

int main(string[] argv)
{
	auto s1 = "中文";//utf8 字符串
	writeln("word:"~ s1); //乱的
	writeln("word:" ~ to!string(toMBSz(text(s1)))); //转后就正常了
    writeln("Hello D-World!");
    return 0;

D language is too unfriendly for Chinese users!
You can't even write gbk files.

There is no example. An example should be added in an obvious position.
I tried for a long time, but couldn't output gbk, and I finally gave up.

To read binary data from a file and dump it into another, you do:

import std.file : read, write;

void[] data = read("infile.txt");
write("outfile.txt", data);

To write binary data to a file:

import std.file : write;

ubyte[] data = [0xA0, 0x0A, 0x30, 0x01, 0xFF, 0x00, 0xFE];
write("myfile.txt", data);

data could contain GBK encoded text, for example. (Just don’t use "Unicode literals".)

Thank you for your reply, but is there any way to output gbk code to the console?
