What is UTF-8, UTF-16, and UTF-32?

Question

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?

Answer 1

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.

Answer 2

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

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

Hope this helps😃

Answer 4

$ααρԋιɾє ☆☆☆ I'm sorry if I wasn't clear. I meant the character encodings, not the HTML <meta> tag.

Answer 5

$ααρԋιɾє ☆☆☆ 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.
