Python+；mako Unicode问题

我正在尝试读取数据库表内容，并使用

mako

和

ball

将其显示为网页。该表中有一些Unicode（utf-8）字段

UnicodeDecodeError('ascii', 'MOTOROLA MILESTONE\xe2\x84\xa2 PLUS', 
                   18, 19, 'ordinal not in range(128)')

使用以下堆栈跟踪：

Traceback (most recent call last):
  File "/workspace/web/controller/bottle.py", line 499, in handle
    return handler(**args)
  File "webserver/webserver.py", line 101, in download
    return html_tmpl(tmpl, **kwds)
  File "webserver/webserver.py", line 116, in html_tmpl
    return tmpl.render(**kwds)
  File "/usr/lib/python2.5/site-packages/Mako-0.3.4-py2.5.egg/mako/template.py", line 189, in render
    return runtime._render(self, self.callable_, args, data)
  File "/usr/lib/python2.5/site-packages/Mako-0.3.4-py2.5.egg/mako/runtime.py", line 403, in _render
    _render_context(template, callable_, context, *args, **_kwargs_for_callable(callable_, data))
  File "/usr/lib/python2.5/site-packages/Mako-0.3.4-py2.5.egg/mako/runtime.py", line 434, in _render_context

  File "/usr/lib/python2.5/site-packages/Mako-0.3.4-py2.5.egg/mako/runtime.py", line 457, in _exec_template

  File "download_android_index_html", line 68, in render_fill_devices
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 18: ordinal not in range(128)

调用函数是：

def html_tmpl(tmpl, **kwds):
    kwds['nav'] = templates_lookup.get_template('nav.html').render()
    kwds['nav_bottom'] = templates_lookup.get_template('nav_bottom.html').render()
    base_path = request.path.replace("de/","").replace("fr/","")
    kwds['languages'] = templates_lookup.get_template('languages.html').render(en_url=base_path,fr_url="/fr"+base_path)
    kwds['analytics'] = ''
    return tmpl.render(**kwds)

我该怎么做呢？我试过：

return tmpl.render_unicode(**kwds)` 

及

运气不好，帮不了什么忙

有什么想法吗？

问题不在于render_unicode无法将python unicode对象转换为utf8，而是存在一个字符串对象，它假定该字符串对象是ascii，并且保存非ascii数据

从头开始-在内部将所有传入字符串解码为unicode。您有一个需要修复的字符串输入

我建议您尝试使用匈牙利符号命名边界处的所有变量，可能是rawstr_myvar和u_myvar

return tmpl.render_unicode(**kwds).encode('utf-8', 'replace')
