DrawText in Japanese

Hi everyone,
I tried to draw a simple text in Japanese using PTB-3 and I received
the following error. Do you have any advice?
Best regards
Luis

Dear Mario,

Thanks for your information.

I created an example that reads some Japanese text
from a file that uses the Shift-JIS character encoding
scheme. It creates a string of Unicode characters,
str, and displays the string. After the computer is
configured to display Japanese (Start-> Control
Panel-> Regional and Languages Options -> Regional
Options : Standards and formats -> Japanese) the
output of disp(str) is correct.

The Shift-JIS character encoding scheme uses multibyte
characters encoding. As the OS/X version of
Screen('DrawText' ) can handle Unicode text encodings
what should I do to use it on windows? All my users
are Japanese and they can't read English.

I was looking at the source files
(PsychWindowTextGlue.h and PsychWindowTextGlue.cc) and
I saw that you ported them from the OS/X version.
Do you have some advice to enable Screen('DrawText' )
can handle Unicode text encodings on Windows?
I'll really appreciate your help.

Best Regards
Luis

The next 'beta' update will probably contain an
improved 'DrawText' implementation for Windoze.
A complete rewrite, there is no shared code between
the OS/X and Windows text renderers, apart from the
very trivial bits you found.

The new drawtext renderer will handle Unicode
encoded text (UTF-16 encoding).

Can you send me a bit of nice demo code which draws
japanese text in Unicode? Are there standard fonts
in Windows to do this?

The trick will be to convert the Unicode text string
into a double - vector, as on OS/X.

If myunicodetext is a textstring, then
Screen('DrawText', window, double(myunicodetext),...);
will draw it.

Dear Mario
Thank you for your information.
I'll wait for next 'beta' update.
Attached is japanese.txt file with Shift-JIS
character encoding.
I tried the trick but I could not succeed.
I used the following code to see the information.
Best regards
Luis
---------

fid = fopen('japanese.txt', 'r', 'n', 'Shift_JIS');
str_jis = fread(fid, '*char')';
fclose(fid);
disp(str_jis);
bytes_str = unicode2native(str_jis);

disp('Press any key...'), pause
screenNum=0;
[wPtr,rect]=Screen('OpenWindow',screenNum);
black=BlackIndex(wPtr);

% Text color and offset
Screen('TextSize', wPtr , 40);
Screen('TextStyle', wPtr , 0);
textcolor=[255 255 255];
voffset=round(rect(4)/20); % vertical offset for each
line of text
hoffset=35; % horizontal offset for
each line of text

Screen('FillRect',wPtr,black);
Screen('DrawText', wPtr, num2str(double(bytes_str)) ,
hoffset, voffset*((2*4)-1),textcolor);
Screen('Flip',wPtr);

while ~KbCheck; end % wait for a key press

Screen('CloseAll');
