This is the one book that every developer who uses Unicode needs.
The general guidelines, compliance standards, and implementation best practices are provided in the core specification. Representative glyphs for each of the Unicode characters are displayed in the code charts. The Unicode Standard Annexes provide comprehensive normative details regarding specific areas of the standard. To help implementers use the Unicode Standard, the Unicode Character Database provides normative and educational data.
In crucial areas like collation (used for sorting, searching, and matching), character set conversion, regular expressions, and the exchange and registration of locale data for different languages and regional cultural norms [CLDR], the Unicode Standard is closely linked to other Unicode software globalization standards. Numerous new Unicode Technical Standards that offer advice and information to aid in the secure implementation of Unicode and develop the registration process for Ideographic Variation Sequences needed by the publishing industry for Chinese and Japanese have considerably improved it.
