What is a key consideration when using symbols and special characters in accessible documents?

Using symbols and special characters in accessible documents requires careful consideration because these elements can often lead to misinterpretation. Screen readers may struggle to interpret symbols, leading to confusion or incorrect information being conveyed to users who rely on these assistive technologies. For instance, an asterisk might be read out as "star" or "asterisk," which could be problematic if it is being used to indicate a footnote or reference. Moreover, variations in how different screen readers interpret symbols can lead to inconsistent experiences for users. Therefore, it is crucial to ensure that symbols and special characters are used sparingly and accompanied by clear text descriptions to enhance understanding and accessibility for all users.

While some symbols may be recognizable, their interpretation can vary greatly among individuals and assistive technologies, which further underscores the importance of clarity in communication.
