What is a Unicode block?

A Unicode block is a contiguous range of code points reserved for a related set of characters, such as Basic Latin, Cyrillic or Emoticons. Each block has a name and a fixed hexadecimal range.

How do I read a code point like U+1F600?

The U+ prefix denotes a Unicode code point written in hexadecimal. U+1F600 is the grinning-face emoji, which falls inside the Emoticons block U+1F600 to U+1F64F.

Is this list exhaustive?

No. It covers the most commonly used blocks for everyday text and emoji. The full Unicode standard defines several hundred blocks. No data is sent anywhere.
