Symboles scientifiques
La création d’une touche morte symboles scientifiques est proposée pour la version 1.1.
Objectif
Certains des symboles mathématiques les plus courants sont présents sur la couche de base du BÉPO. Toutefois, une grande partie des symboles très couramment utilisés en sciences exactes, en mathématiques et dans certains domaines techniques présents dans Unicode en sont absents. La plupart d’entre eux sont en fait saisis soit en utilisant des menus avancés de WYSIWYG, soit des outils nécessitant une compilation, notamment LaTeX. Cela ne répond toutefois que partiellement au besoin, puisqu’une partie des échanges se fait dans d’autres outils, par exemple par courriel (où lire du LaTeX peut rapidement devenir malaisé). La touche morte grec répond partiellement au problème (mathématiciens et scientifiques ont souvent recours à des caractères grecs), mais de nombreux symboles fréquents restent inaccessibles.
