Re: How-to: input/output "Japanese Characters"?
"Georg Wrede" Sorry, somebody else has to help, I'm not using Windows. :/ LOL! You actualy helped a lot. You are not using Windows ! It works on Linux but not on Windows. Now, it may work on Windows too. But stream.d must be modified to take care of the differences between the following cases: reading/writing to the console (true stdin/stdout) reading/writing to stdin/out redirected and probably some others (undocumented) quirks... After some reading on MSDN, i have done some testing and it works for me now. Have a very nice Linux Day... :-) Thanks.

Works with your Japanese strings. It just works(tm).
I am trying this on a North American WinXP station.
I am using DMD V1.

You will find a small program at the end of this
message who does not work for me.
The console use Lucida COnsole font. The CP is 65001.
cmd.exe can read/write utf strings, but not my
program.
I want to be able to read an utf string from stdin.
That string will contains characters > 256, ie glyphs
you can only see with an unicode font.
I have read some documentation on MSDN that confirm
it can't work. So why does it work for you ?
Can anyone, explain to me what am i doing wrong ?
Thanks a lot...

Interesting... for whatever reason I thought I had to cast/convert
to!dstring in order to get the correct output. Which kept resulting in:
std.utf.UtfException: 4invalid UTF-8 sequence
thank you very much.
