## Overview

This repository is a data distribution of Adobe character-map resources, not an application runtime. A consumer selects a collection’s CMap for its character encoding; the map converts character codes to CIDs for a compatible CIDFont, whose Registry and Ordering must match. Collections also provide tabular CID-to-code mappings, and Japan1 includes mappings for JIS standards. The README documents these uses and compatibility rules; no source excerpts were provided, so the graph shows documented relationships only.

Main entry points: [`Adobe-Japan1-7/CMap`](https://github.com/adobe-type-tools/cmap-resources/tree/master/Adobe-Japan1-7/CMap) (Japan1-7 CMaps), [`Adobe-CNS1-7/CMap`](https://github.com/adobe-type-tools/cmap-resources/tree/master/Adobe-CNS1-7/CMap) (CNS1-7 CMaps), [`Adobe-GB1-6/CMap`](https://github.com/adobe-type-tools/cmap-resources/tree/master/Adobe-GB1-6/CMap) (GB1-6 CMaps), [`deprecated/Adobe-Japan2-0/CMap`](https://github.com/adobe-type-tools/cmap-resources/tree/master/deprecated/Adobe-Japan2-0/CMap) (Deprecated Japan2-0)
