What is UTF-8, UTF-16, and UTF-32?
I've heard a lot about unicode and character encodings, but I'm still a little shaky on the whole unicode topic. Can somebody explain?

Unicode is a character set or character encoding. In Unicode, each literal character is mapped to a single code point.
e.g A => U+0041
UTF-8 represents a code point as a numeric value of 2, 3 or 4 bytes. It is the most compatible with ASCII.
UTF-16 represents a code point as a numeric value of 2 or 4 bytes.
UTF-32 has a fixed size/width of 4 bytes per character code point.

SapphireBlue character encoding is associated with a meta tag....

The <meta>Ā tagĀ provides metadata about the HTML document. Metadata will not be displayed on the page, but will be machine parsable.Ā MetaĀ elements are typically used to specify page description, keywords, author of the document, last modified, and other metadata.

$Ī±Ī±ĻŌĪ¹É¾Ń āāā More like the other way around; character encoding is a broader topic than the HTML <meta> tags.
Again, if I wasn't clear, your response doesn't answer my question.
