Error while displaying special characters

[L30Bola]

So I have file with characters like ê õ á ç ì. When I start grip it looks normal (* Running on http://localhost:6419/ (Press CTRL+C to quit)) but when I open the browser window and navigate to localhost:6419, it gives me a 500 Internal Error. On the terminal windows this is the Traceback:

This error only shows up on Windows (tested on Windows 10, Firefox/Chrome). On my Linux (Fedora 23) it is working without issues.

Thank you for documenting this error @L30Bola. I also had this issue for “ and ”, but I wouldn't even have guessed it if you hadn't documented this bug.

[skandix]

is this something that is prioritized to fix? It occurs both in python 2.7 and python 3.4.. it triggers on my norwegian special characters 'æ ø å'
