当我重命名一个克隆站点的名称时出现 UnicodeDecodeError

Question

Plone 4.2.5从4.1.4升级，default_language为zh-cn，default_charset为utf-8（portal_properties/site_properties）。

当我尝试在 ip:8080/ 的根页面中重命名 Plone 站点的名称时，会显示站点错误：

An error was encountered while publishing this resource. 
Error Type: UnicodeDecodeError
Error Value: ('ascii', '\xe8\xa2\x81\xe4\xba\x88\xe6\xb9\x98', 0, 1, 'ordinal not in range(128)')

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe8 in position 0: ordinal not in range(128)

当我尝试将一些文件夹导入新创建的 Plone 站点时，曾发生过与 UnicodeDecodeError 相关的问题。

我成功地重命名了另一个 Plone 站点的名称。我不知道它们之间有什么区别。 :(

您的网站有时会将 unicode 内容编入目录索引中，从而有效地破坏了它们。这可能是由于旧的 Plone 错误，或者是附加组件或自定义代码出错。

您可以尝试在默认 Python 编码设置为 UTF-8 的情况下运行完整的重新索引来解决此问题。 以下不是生产现场的推荐程序；这只是解决您问题的临时“石膏”。

在您的 Python site-packages 目录中，添加一个名为 sitecustomize.py 的文件，其内容为：

import sys

sys.setdefaultencoding('utf8')

然后重新启动您的克隆站点并尝试重命名或首先执行完整的目录重新索引。

记得再次删除sitecustomize.py 文件。在 Python 中设置默认编码只会掩盖未来的问题。
