Difference between utf8 vs base 64, and include base 64 encoded string in HTML

 UTF-8 and UTF-16 are methods to encode Unicode strings to byte sequences.

See: The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!)

Base64 is a method to encode a byte sequence to a string.

So, these are widely different concepts and should not be confused.

Things to keep in mind:

• Not every byte sequence represents an Unicode string encoded in UTF-8 or UTF-16.

• Not every Unicode string represents a byte sequence encoded in Base64.
