Information technology — Keyboard layouts for office systems — Part 11: Functionality of dead keys and repertoires of characters entered by dead keys

Introduction

The data from this file have been extracted from the French Wikipedia article about ISO/CEI 9995

Data is embedded as python script for easier programatic usage. Combining diacritics are defined after a circle (◌, U+25CC) rather than the usual non-breaking space (U+00A0) for easier reading.

Combinaisons de touches mortes avec le caractère d’espacement

From ISO/CEI 9995-11, § 5.2.
