hello!
i use dmd 0.127 under Windows XP.
i need analyse command lime parameters in my program.
i use main() parameters char[][] args for this.
but it seems it not works with non-english letters.
Test program:
///// test.d /////
void main(char[][] args)
{
int len1 = args[1].length;
int len2 = args[2].length;
int len3 = args[3].length;
printf("len1=%d, len2=%d, len3=%d", len1, len2, len3);
}
////////
When i run it as
test.exe param1 param2 param3
then it print to console
len1=6, len2=6, len3=6
When i replace word "param" by national letters (same length)
test.exe парам1 парам2 парам3
then it print to console
len1=1, len2=6, len3=6
First parameter length wrong :(
Is it bug?

I've complained about this before because there appears to be an easy solution. If D would just use GetCommandLineW(), which IS supported on win9x/me and NT, and convert it to UTF-8, Windows would convert from the current charset. While this solution would make main(args[]) happy, you'd need to set your terminal to UTF-8 in order to writef() correctly, but that's not such a big deal because it won't result in an exception.

In Delphi i have not any problems with non-english letters, excsept oem<->ansi conversion.

Is it somehow different from an MS-DOS window under Win9x, such that it makes sense to use UTF-8 with it? Moreover, can console apps under XP auto-detect the terminal encoding? And can it be done in such a way that the app will work under 9x as well? We ought to have an I/O system that supports different encodings.
