newlines are normalized to one end of line sequence which is per default UNIX style (\n). Python 2.x supports two ways of representing string objects. One is the str type and the other is the unicode autoescape block (see Autoescape Overrides). 2.5 Notes on Identifiers Jinja2 uses the regular Python 2.x naming rules. Valid identifiers have to match [a-zA-Z_][a-zA-Z0-9_]*. As a matter of fact non ASCII The reason why the filename and error message are bytestrings and not unicode strings is that Python 2.x is not using unicode for exceptions and tracebacks as well as the compiler. This will change with Python
