so trying use jinja2 simple html template keep getting error when call render():
warning: ironpythonevaluator.evaluateironpythonscript operation failed. traceback (most recent call last): file "c:\program files (x86)\ironpython 2.7\lib\jinja2\jinja2\loaders.py", line 125, in load file "c:\program files (x86)\ironpython 2.7\lib\jinja2\jinja2\environment.py", line 551, in compile file "c:\program files (x86)\ironpython 2.7\lib\jinja2\jinja2\environment.py", line 470, in _parse file "c:\program files (x86)\ironpython 2.7\lib\jinja2\jinja2\parser.py", line 31, in __init__ file "c:\program files (x86)\ironpython 2.7\lib\jinja2\jinja2\environment.py", line 501, in _tokenize file "c:\program files (x86)\ironpython 2.7\lib\jinja2\jinja2\environment.py", line 494, in preprocess file "<string>", line 21, in <module> file "c:\program files (x86)\ironpython 2.7\lib\jinja2\jinja2\environment.py", line 812, in get_template file "c:\program files (x86)\ironpython 2.7\lib\jinja2\jinja2\environment.py", line 786, in _load_template unicodeencodeerror: ('unknown', '\x00', 0, 1, '') now understand jinja2 works utf-8 forcing python code formatting:

this known bug in ironpython. can work around editing jinja2 source:
using jinja2 on ironpython non-ascii characters in template result in error. replace
to_string = unicodeto_string = lambda x: unicode(x)near top of runtime.py work around issue.
