Hi Harrison, great tutorial.
i have a very annoying problem, i'm trying to build my website in french. but when i write words with special characters (like é or è), i get a ""UnicodeDecodeError: 'utf8' codec can't decode byte 0xe9 in position 1482: invalid continuation byte"".
i also added # -*- coding: utf-8 -*- in the top of every file, but it did not solve the problem.
please help me.

I am guessing the reason you would have problems consistently getting your 500.html is because 500 is a Server error as opposed to a page error with a 404. If the server is having problems accessing your templates location i doubt it would be able to render the 500.html. My idea anyway.

Just wondering: is it possible (and advisable) to have a single html page dealing with all types of html/server errors? (in which case, a function in the __init__ file would have a few if statements to classify the error and the error message would have to be passed to the HTML to Jinja via a variable. what do you think?

hey Great video, quick question, when i put a tab space behind try statement it throws an error, but when i put four spaces it works? DO you know why that might be happening because i have used tab for indentation in python all the time

[arjunbemarkar]

why not put the try except in the if __name__ == "__main__" thing?

what does the value carried by "e" parameter in page_not_found

[Arslanqadri]

it is possible to log the errors in an error file concurrently?

Hi Harrison

Do you do anything fancy to help search engines find your websites?....egI have read about using schema but it just looks annoying :)

are you simply copy/pasting stuff from Miguel's tutorial?
