问个python i18n的问题

winshton

做了个中英文切换的测试,在命令行下执行就正常,在eclips+pdev下运行就出错,提示错误:  File "C:\Documents and Settings\Administrator\Desktop\testtt\src\test.py", line 9, in <module>
    print _("File")
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-1: ordinal not in range(128)
直接print "中文"就能正常显示
修改coding utf-8 和gb.po的Content-Transfer-Encoding: cp936都无效.
文件:test.py如下:
# -*- coding: GBK -*-
#!/usr/bin/env python


import gettext
gettext.install('gb', './locale', unicode=False)
gettext.translation('gb', './locale', languages=['cn']).install(True)

print _("File")
#print "中文"

翻译文件gb.po如下:
# SOME DESCRIPTIVE TITLE.
# Copyright (C) YEAR ORGANIZATION
# FIRST AUTHOR <EMAIL@ADDRESS>, YEAR.
