Unicode characters in latex documents

gistfile1.txt

Instead of using:

\usepackage[utf8]{inputenc}
\usepackage{babel}

use:
 
\usepackage{fontspec}
\usepackage{polyglossia}

which are more recent implementations. You also need to set a font that
has all the characters you want to use. For example:

\setmonofont{DejaVu Sans Mono}[Scale=MatchLowercase]

and use lualatex or xelatex to compile
