How this entity was disambiguated

This entity first appeared as the object of triple T188956 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07

Target entity: Unicode Character Database
Context triple: [Unicode, includesDatabase, Unicode Character Database]

A. Unicode
Unicode is a universal character encoding standard that assigns unique code points to virtually all written scripts, symbols, and emojis used in modern computing.
B. ISO/IEC 10646
ISO/IEC 10646 is an international standard that defines the Universal Coded Character Set (UCS), a comprehensive repertoire of characters used worldwide and closely aligned with the Unicode Standard.
C. Unicode Consortium
The Unicode Consortium is a non-profit organization that standardizes the representation of text and symbols in digital systems worldwide through the Unicode Standard.
D. Unicode Scalar Values
Unicode Scalar Values are the set of valid Unicode code points (excluding surrogate code points) that uniquely identify abstract characters in the Unicode standard.
E. Latin-1 Supplement
Latin-1 Supplement is a Unicode block that extends the basic Latin script with additional characters, including accented letters and symbols used in many Western European languages.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
