UTF-8 is like the other UTF encodings a character encoding to encode characters of the Unicode character set UCS. Base64 is an encoding to represent any byte sequence by a sequence of printable characters (i.e. A – Z , a – z , 0 – 9 , + , and / ). There is no System. Text.

What is UTF-8 data?

UTF-8 is a variable-width character encoding used for electronic communication. UTF-8 is capable of encoding all 1,112,064 valid character code points in Unicode using one to four one-byte (8-bit) code units. Code points with lower numerical values, which tend to occur more frequently, are encoded using fewer bytes.

Should I use UTF-8 or utf8mb4?

For the foreseeable future you need to use utf8mb4 to ensure correct UTF-8 encoding. After sufficient time has passed, the current utf8 will be removed, and at some future date utf8 will rise again, this time referring to the fixed version, though utf8mb4 will continue to unambiguously refer to the fixed version.

Which is better UTF-8 or utf8mb4?

In Unicode terms, utf8 can only store characters in the Basic Multilingual Plane, while utf8mb4 can store any Unicode character. Unicode isn’t without its problems, but it’s the best option available. utf8mb4 is 100% backwards compatible with utf8.
