You should really use a proper templating system. Jinja2 is included with AppEngine.

Answer 2

Here you got solution.

>>> "t".decode("utf-8")
u't'
>>> "\x81".decode("utf-8")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "encodings/utf_8.py", line 7799, in decode
UnicodeDecodeError: 'utf8' codec can't decode byte 0x81 in position 0: unexpected code byte

>>> "a\x81b".decode("utf-8", "replace")  # this will decode better and the right way.
u'a\ufffdb'

Set default encoder at the top of your code

In appcfg.py which resides inside /google/appengine/tools/appcfg.py

on line 73 add

import sys
reload(sys)
sys.setdefaultencoding("ISO-8859-1")
