Answer 1

UTF-8 or UTF-16 are both good choices. They both give you access to the full range of Unicode code points without using up 4 bytes for every character.

Your choice will be influenced by the language you're using and its support for these formats. I believe UTF-8 plays best with ASP.NET overall, but it will depend on what you're doing.

UTF-8 is often a good choice overall because it plays well with code that expects only ASCII, whereas UTF-16 doesn't. It is also the most efficient way of representing content largely consisting of our English alphabet, while still allowing the full repertoire of Unicode when needed. A good reason for choosing UTF-16 would be if your language/framework used it natively, or if you're going to be mainly using characters that aren't in ASCII, such as Asian languages.
