Subject: [I18n-sig] Python3.0.1.1 is not available when system locale is

Message-ID: <D4BD5E561A848848843C11CBF0BAD971581018@AUSYMS12.ca.com>

Dear all,
 
Have you meet a problem that Python3.0.1.1 is not available when system locale is zh_TW.eucTW?
 
I just downloaded Python3.0.1 source code and compiled it on my Debian 5.0 Linux using following commands:
root at li-le01-d5:~# ./configure
root at li-le01-d5:~# make
root at li-le01-d5:~# make altinstall
 
Then I try Python in interactive mod and found the problem. On my system, there is not any output and error message in python3.0 console when I try to execute some statments. See following screen reaction:
root at li-le01-d5:~# python3.0
Python 3.0.1 (r301:69556, May 26 2009, 19:48:24)
[GCC 4.3.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import locale
>>> loacle.getlocale()
>>> help()
>>> exit()
>>> 
 
Then I try to execute a script file hello.py.
My script contains only one python statement: print('Hello World!')
On my system, there is not any output and error message also when I run "python3.0 hello.py".
root at li-le01-d5:~# locale
LANG=zh_TW.EUC-TW
LC_CTYPE="zh_TW.EUC-TW"
LC_NUMERIC="zh_TW.EUC-TW"
LC_TIME="zh_TW.EUC-TW"
LC_COLLATE="zh_TW.EUC-TW"
LC_MONETARY="zh_TW.EUC-TW"
LC_MESSAGES="zh_TW.EUC-TW"
LC_PAPER="zh_TW.EUC-TW"
LC_NAME="zh_TW.EUC-TW"
LC_ADDRESS="zh_TW.EUC-TW"
LC_TELEPHONE="zh_TW.EUC-TW"
LC_MEASUREMENT="zh_TW.EUC-TW"
LC_IDENTIFICATION="zh_TW.EUC-TW"
LC_ALL=
root at li-le01-d5:~# /usr/local/bin/python3.0 hello.py
root at li-le01-d5:~#
 
Then I witch to zh_TW.utf8 and try it again. The problem does not occur.
root at li-le01-d5:~# LANG=zh_TW.utf8
root at li-le01-d5:~# locale
LANG=zh_TW.utf8
LC_CTYPE="zh_TW.utf8"
LC_NUMERIC="zh_TW.utf8"
LC_TIME="zh_TW.utf8"
LC_COLLATE="zh_TW.utf8"
LC_MONETARY="zh_TW.utf8"

LC_ADDRESS="zh_TW.utf8"
LC_TELEPHONE="zh_TW.utf8"
LC_MEASUREMENT="zh_TW.utf8"
LC_IDENTIFICATION="zh_TW.utf8"
LC_ALL=
root at li-le01-d5:~# /usr/local/bin/python3.0 hello.py
Hello world!
root at li-le01-d5:~#
 
This problem was also occurs when I try the same steps on HP-UX 11.11, SUSE sles10, Ubuntu 9.04.
Have you meet the same problem? Would you please kindly to tell me if I missed some steps when I compile Python from source or some env variables from shell or some others.
The problem was strange and made me crazy. I am very appreciated if you can tell me how to resolve it.
 
Thank you very much.
Leeon

You did everything correctly; I can reproduce the problem.

The source of the problem is that Python does not support the EUC-TW
encoding. Unless a codec for that encoding is contributed, there is no
chance to run Python 3 in that locale. Python 3.1 will abort execution
with the error message

Fatal Python error: Py_Initialize: can't initialize sys standard streams
LookupError: unknown encoding: EUC-TW
