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 ïàðàì1 ïàðàì2 ïàðàì3

then it print to console
len1=1, len2=6, len3=6

First parameter length wrong :(
Is it bug?

Seems to be a bug in the parameter handling by dmc:
first non-ascii sequence of characters is suppressed.

gcc does not have this problem.

Currently, D expects everyone to set their terminal to UTF-8.

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.

Again and again :(
Every time i use user input or works with filenames in D i realize, that default
UTF-8 strings - big pain (for me at least). In Delphi i have not any problems
with non-english letters, excsept oem<->ansi conversion.

This would enable Win9x apps to use Unicode command lines, but since Win9x DOS windows can't use UTF-8, it would break the hello.d example.

Nonetheless, I've started working on something to this effect....

How does the Windows XP "terminal" work?  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.  See my little conversation with Uwe Salomon starting here:

By the way, did you already decide if you want to work on a TextStream? Just curious... :)

Ciao

Sorry, I was away for the weekend, and so haven't had much time to look at the possibility.  But I will soon.
