MacOSX encoding problem

[EDIT: 20110626 09:40 CDT - reformat - WDR]

Hello everebody, I have an encoding trouble.

 *>> ver* 

-------------------------------------------------------------------------------------
MATLAB Version 7.12.0.635 (R2011a)
Operating System: Mac OS X  Version: 10.7 Build: 11A511 
Java VM Version: Java 1.6.0_26-b03-383-11A511 with Apple Inc. Java HotSpot(TM) 64-Bit Server VM mixed mode

mac console:

DeZhMBP:~ clock$ locale
LANG="ru_RU.UTF-8"
LC_COLLATE="ru_RU.UTF-8"
LC_CTYPE="ru_RU.UTF-8"
LC_MESSAGES="ru_RU.UTF-8"
LC_MONETARY="ru_RU.UTF-8"
LC_NUMERIC="ru_RU.UTF-8"
LC_TIME="ru_RU.UTF-8"
LC_ALL="ru_RU.UTF-8"

It seems to me that UTF8 is a correct encoding for my OS.

MATLAB console:

>> getenv('LANG')

ans =

ru_RU.KOI8-R

OK, trouble is here, I set up a startup.m in my start folder:

bdclose all; 
set_param(0, 'CharacterEncoding', 'UTF-8');
slCharacterEncoding('UTF-8');

Restart MATLAB and again:

>> getenv('LANG')

ans =

ru_RU.KOI8-R

I try to set manually:

>> bdclose all; 
set_param(0, 'CharacterEncoding', 'UTF-8');
>> getenv('LANG')

ans =

ru_RU.KOI8-R

I can write m-scripts using my native language. Its OK, but command window shows me: -0.0092942 3.0647 . .

I do not understand what should I do to improve it. I need UTF-8 for platform sharing. Any ideas?

Please help.

A little bit more info:

>> feature('DefaultCharacterSet')

ans =

UTF-8

>> disp привет

>> getenv('LANG')

ans =

ru_RU.KOI8-R

[Denis Zhegalin]

modified ~/.profile

cat > ~/.profile LANG=ru_RU.UTF-8

modified environment.plist

LANG ru_RU.UTF-8

[Denis Zhegalin]

now I have a startup script:

bdclose all;

set_param(0, 'CharacterEncoding', 'UTF-8');

slCharacterEncoding('UTF-8');

feature('DefaultCharacterSet','UTF-8');

setenv('LANG','ru_RU.UTF-8');

But still have:

>> getenv('LANG')

ans =

ru_RU.UTF-8

>> disp привет

I've added to startup.m all LC_XXXXXX variables connected with locale.

>> !locale

LANG="ru_RU.UTF-8"

LC_COLLATE="ru_RU.UTF-8"

LC_CTYPE="ru_RU.UTF-8"

LC_MESSAGES="ru_RU.UTF-8"

LC_MONETARY="ru_RU.UTF-8"

LC_NUMERIC="C"

LC_TIME="ru_RU.UTF-8"

LC_ALL=

I've put the same into environment.plist, ~/.bashrc, ~/.profile and even launched.conf. And again have the same result. And I don't have troubles with other software with encoding.

Colleagues?

The MathWorks locale database can be found at the following location and name.

   $matlabroot/bin/lcdata.xml

Find the following entry.

     <locale name="ru_RU" encoding="KOI8-R" xpg_name="ru_RU.KOI8-R">
         <alias name="ru"/>
         <alias name="ru_SU"/>
     </locale>

Modify as the following.

     <locale name="ru_RU" encoding="UTF-8" xpg_name="ru_RU.UTF-8">
         <alias name="ru"/>
         <alias name="ru_SU"/>
     </locale>

That's it.

This issue is fixed as of R2020a when MATLAB on Mac atarted using UTF-8 as the default encoding.
