UTF8 or UTF-8? [closed]

Question

Which of the two is correct terminology?

Answer 1

That depends on where you use it...

The name of the encoding is UTF-8.

A dash is not valid to use everywhere, so for example in .NET framework the property of the System.Text.Encoding class that returns an instance of the UTF8Encoding class that handles the UTF-8 encoding is named UTF8.

Answer 2

It's definitely UTF-8. UTF8 is only used commonly in places where a dash is not allowed (programming language indentifiers) or because people are too lazy.

Answer 3

Following the RFC standard the answer is UTF-8

Answer 4

I believe according to the Unicode Consortium, it's UTF-8.

Answer 5
