Annotation of Easily Confused CJK Unified Ideographs

Introduction

First submitted as IRGN2206 Proposal for Annotating Easily Confused Ideographs, there exist lots of easily confusable characters, especially in Extension B, that were rightfully disunified for having different semantics (IRG terminology: "non-cognate") per their original source.

Easily Confusables, i.e. characters with similar shape, in accordance to the principles set out in Annex S, which are disunified in CJK Unified Ideographs Extensions (i.e. not subject to the Source Separation Rule), may be annotated to reflect the difference in semantic meaning owing to its disunification. The semantic meaning may be applicable to all locales, or only the locales for which a representative glyph appears.
