不是报表模板的问题，报表模板没有动过
新安装，什么也不做，就会这样 -
我这样弄的：
<br /> dt_text = unicode( self.lang_obj.date_format+ " " + self.lang_obj.time_format, 'utf-8' )<br /> return datetime.strftime(dt_text)<br />
不行，结果是这样：

从以上你贴出的log中可以看到在report_sxw.py模块的第251行用了str(value), 而这个value中应该有无法用ASCII编码的unicode字串（中文日期格式），str()默认使用ASCII来编码该字串从而导致错误。你可以试试用：from tools import ustr<br />ustr(value)
来替代这行代码，试试。
我的没有装5.x的版本，你可以试试，看看结果如何 -
Hi digitalsatori，
结果是这样：

strftime 不支持unicode 参数 -
不好意思value本来就是unicode string了，应该encode成byte string
硬编码试试value.encode('utf8')
