python - 在odoo开发中，我每次创建数据的时候，都会出现这样的xml编码错误

Question

我已经创建了model对象和对应的xml，但是在odoo首页点击Create按钮添加数据对象时，出现如下错误:

ValueError: All strings must be XML compatible: Unicode or ASCII, no NULL bytes or control characters

系统规范:

• Ubuntu16.04。 2
• Odoo 版本为 10.0
• python解释器是2.7
• lxml版本为3.5.0
• pycharm版本为2018
• Chrome 版本为 50.0.2661.102(64 位)

sudo locale时，出现这些
LANG=zh_CN.UTF-8
LANGUAGE=zh_CN:en_US:en
LC_CTYPE="zh_CN.UTF-8"
LC_NUMERIC=zh_CN.UTF-8
LC_TIME=zh_CN.UTF-8

Answer 1

通过使用 u'your_label':

 help=u'简要描述发现的bug'

 _description = u'bug阶段'

string=u'所需时间(小时)'

fields.Selection([('waiting',u'未开始'),('doing',u'进行中')....

我也在用阿拉伯语编码，我总是使用 Unicode 作为我的标签以避免这个问题。
