Summary: UTF-8 output to console is seriously broken
Product: D
Version: 1.020
Platform: PC
OS/Version: Windows
Status: NEW
Severity: normal
Priority: P2
Component: Phobos
AssignedTo: bugzilla digitalmars.com
ReportedBy: a.solovey gmail.com
If windows console code page is set to 65001 (UTF-8) and program outputs
non-ascii characters in UTF-8 encoding, there will be no more output after the
first new line after accented character. I believe that problem is in
underlying DMC stdio, but it is more disturbing with D as it has good Unicode
support and it is very convenient to work international texts in it.
This problem has been reported in newsgroup several times before, see for
example
http://www.digitalmars.com/d/archives/digitalmars/D/announce/openquran_v0.21_8492.html
Here is the code to illustrate the problem:
////////
import std.c.stdio;
import std.c.windows.windows;
extern(Windows) export BOOL SetConsoleOutputCP( UINT );
void main() {
SetConsoleOutputCP( 65001 ); // or use "chcp 65001" instead
// Codepoint 00e9 is "Latin small letter e with acute"
puts( "Output utf-8 accented char \u00e9\n... and the rest is cut off!\n"
);
}
/////////
If you run it, "... and the rest is cut off!" won't be displayed. Do not forget
to set console font to Lucida Console before trying this.

The problem doesn't show if I use the Windows API (either WriteConsole or
WriteFile) to output. So the bug must be somewhere in DM's stdio
implementation.

I hope this gets fixed one day. Here is an updated example, where it still
doesn't work (for stderr, stdout is ok) as of DMD 1.035
import std.c.stdio;
import std.c.windows.windows;
extern(Windows) export BOOL SetConsoleOutputCP( UINT );
void main() {
SetConsoleOutputCP( 65001 ); // or use "chcp 65001" instead
// Codepoint 00e9 is "Latin small letter e with acute"
fputs("Output utf-8 accented char \u00e9\n... and the rest is OK\n",
stdout);
fputs("Output utf-8 accented char \u00e9\n... and the rest is cut off!\n",
stderr);
fputs("STDOUT.\n", stdout);
fputs("STDERR.\n", stderr);
}

Sort of works for me.
The text doesn't get cut off, but the unicode characters don't get displayed
either.
C:\Users\Kevin\Documents\D Projects\ConsoleApp1\ConsoleApp1\bin>ConsoleApp1.exe
Output utf-8 accented char é
... and the rest is OK
Output utf-8 accented char ��
... and the rest is cut off!
STDOUT.
STDERR.

Version|1.020 |D1 & D2
Status update as of DMD 2.062 (Win XP 32 bit)
Still the same error for the above mentioned example, however, when modified to
use write instead of fputs:
import std.stdio;
import std.c.windows.windows;
extern(Windows) BOOL SetConsoleOutputCP( UINT );
void main() {
SetConsoleOutputCP( 65001 ); // or use "chcp 65001" instead
stderr.write("STDERR:Output utf-8 accented char \u00e9\n... and the rest is
cut off!\n");
stderr.write("end_STDERR.\n");
}
I get this error:
STDERR:Output utf-8 accented char é
... and the rest is cut off!
std.exception.ErrnoException D:\PROGRAMS\DMD2\WINDOWS\BIN\..\..\src\phobos\std\stdio.d(1264):
(No error)
----------------
0x0040D874
0x0040D6FF
0x00402218
0x00402189
0x00402121
0x00402030
0x0040354E
0x00403151
0x00402388
0x7C81776F in RegisterWaitForInputIdle

So if anybody have a clue what's going on there...

I can confirm this issue. When enumerating a directory (via dirEntries())
containing a file with a character in the CP850/CP1252 space (e.g. "säb"),
depending on the codepage settings, the output is as follows:
chcp 1252 => output is "säb" (Unicode encoding for "ä")
chcp 65001 => output is
"säbstd.exception.ErrnoException D:\tools\d\bin\..\src\phobos\std\stdio.d(1352):
(No error)"
In both cases e.g. cmd's dir shows the correct results.
The correct results are also shown when using - not really comparable - C with
printf().
Tried the case in cmd, console2, and conemu. All show the same results.
It'd really be nice if this bug would get fixed...
