Introduce support for non-Latin characters

[qurbat]

As of now, search results that contain Unicode characters (i.e. most non-Latin languages, e.g. Hindi, Arabic, Greek, Hebrew . . .) as part of the description, domain name (IDNs), or URL. do not render properly.

Example (with Greek characters)

I've introduced this change in PR #7 to address this. Instead of printing the final_string variable directly, it is now passed to the html.unescape() function from within the print call.
