For the full list of emoji characters, see emoji additions for Unicode 11.0, and Emoji Counts. For a detailed description of support for emoji characters by the Unicode Standard, see UTS #51, Unicode Emoji. Version 11.0 also includes other improvements for emoji handling:

• a mechanism to request the glyph direction for emoji
• descriptions of the four new emoji hair components
• descriptions of gender neutral emoji
• simplified statements of emoji-related rules for grapheme cluster boundaries and for word boundaries.

Three other important Unicode specifications have been updated for Version 11.0:

• UTS #10, Unicode Collation Algorithm — sorting Unicode text
• UTS #39, Unicode Security Mechanisms — reducing Unicode spoofing
• UTS #46, Unicode IDNA Compatibility Processing — compatible processing of non-ASCII URLs

Unicode 11.0 includes a number of changes. Some of the Unicode Standard Annexes have modifications, often in coordination with changes to character properties. In particular, there are changes to:

• UAX #14, Unicode Linebreaking Algorithm
• UAX #29, Unicode Text Segmentation
• UAX #31, Unicode Identifier and Pattern Syntax

The Unicode Standard is the foundation for all modern software and communications around the world, including all modern operating systems, browsers, laptops, and smart phones—plus the Internet and Web (URLs, HTML, XML, CSS, JSON, etc.). The Unicode Standard, its associated standards, and data form the foundation for CLDR and ICU releases.
