UTF-8 encodes Unicode characters into a sequence of 8-bit bytes. The standard has a capacity for over a million distinct codepoints and is a superset of all characters in widespread use today. By comparison, ASCII (American Standard Code for Information Interchange) includes 128 character codes.

What does u+ mean in Unicode?

Unicode code points
The “U+” notation is useful. It gives a way of marking hexadecimal digits as being Unicode code points, instead of octets, or unrestricted 16-bit quantities, or characters in other encodings. It works well in running text. The “U” suggests “Unicode”.

To insert a Unicode character, type the character code, press ALT, and then press X. For example, to type a dollar symbol ($), type 0024, press ALT, and then press X. For more Unicode character codes, see Unicode character code charts by script.

Does UTF-8 include Chinese?

Should I use UTF-8 or ASCII?

UTF-8 is but a single encoding of that standard, there are many more. UTF-16 being the most widely used as it is the native encoding for Windows. So, if you need to support anything beyond the 128 characters of the ASCII set, my advice is to go with UTF-8.

Is Unicode better than ASCII?

The main difference between Unicode and ASCII is that Unicode is the IT standard that represents letters of English, Arabic, Greek (and many more languages), mathematical symbols, historical scripts, etc whereas ASCII is limited to few characters such as uppercase and lowercase letters, symbols, and digits(0-9).
