Goal
- Enable content to be rendered correctly in screen readers.
- Promote content indexing by search engines.
- Promote content recognition by artificial intelligence components.
Some content production tools, particularly those used for publishing on social media, do not allow content to be formatted with options such as bold or italics. To get around this limitation, it is possible to use Unicode mathematical and other characters, which simulate formatting. The visual rendering of this type of content is certainly more varied, but it makes the content incomprehensible in screen readers and, more generally, for tools used to index or manipulate content.
