you don't have unicode strings, have byte strings. python tries implicitly decode using standard ascii codec. explicitly decode them:

{% if(backpaths) %} {%   n in backpaths:%} {{       n.decode('utf8') }} </br> {%   endfor %} {% endif %}

it'll better if passed in backpaths template ready-decoded.
