Fix for handling non-Latin characters

[qurbat]

This change introduces support for search results containing non-Latin characters as part of the URL or description.

This is done by passing the final_string variable to the html.unescape() function (instead of printing it directly) at the last print call.

@deepseagirl could you merge this after review?

@deepseagirl hi, just sending a ping on this. thanks!

@deepseagirl Can we close this?

[deepseagirl]

hi, thanks. this is a good improvement :)
i moved the unescape to only occur on the result descriptions directly
with a flag to toggle the behavior on/off

new default will be to decode character references:

$ python3 degoogle.py "intitle:⟿ inurl:⟿"
-- 9 results --

flag to turn decoding off:

$ python3 degoogle.py -d "intitle:⟿ inurl:⟿"
-- 9 results --

the html.unescape python doc links to this list of named character references which seemed handy.
i didn't realize char references were such an in depth thing until now. if you're interested here is that link
