This sets the character set for the document.

You can find more info on that over on w3schools.

Hope that helps :)

It's important for internationalisation. It tells what character set to expect from your content within the page.

For example these letters used in european languages could not be found in an old ASCII character set: èéòàù (the one up to 127, not the one up to 255).

Different languages have many characters that are not part of the ASCII character set or other sets used later on but the UTC-8 is today's best bet since according to wikipedia "82.4% of all Web pages in January 2015" use it and it covers almost all languages.
