The typographic pictograms are provided with an appropriate alternative.
Le recours aux web fonts (polices de caractères téléchargeables) a considérablement facilité le recours à une astuce technique très appréciée du point de vue des performances : remplacer les images de diverses icônes par un caractère UTF-8 graphique obtenu grâce à une police spécifique. However, this involves significant risks, including accessibility risks, if you do not make sure that a textual alternative is created to this character that was stunned from its meaning by default.
Objectives
Improve accessibility of content to readers with disabilities.
Implementation
Test the text with the relevant character(s) with the sound rendering of the playback software.
If the software does not recognize the character, then content will be hidden from display via CSS.
Control
Directly review the code to verify that each icon displayed via a font is provided with an alternative in HTML content.
