This tool helps you mark up your content according to the W3C's WAI-Adapt: Symbols Module specification. This will enable people who need symbols to help them understand content to access your content.
WAI-Adapt is working on a range of techniques to help you make your content more accessible. For general information, please check out the WAI-Adapt Explainer.
Please note that this is a proof-of-concept tool that shows how such an editor can work. You're welcome to use it to mark up your content, but be aware that work on developing guidance on marking up your content is ongoing, and the specification is not yet final.
