The small arrow that is displayed inside the quote BBCode that is used as a link to the post being quoted results in a poor accessibility experience. The anchor tag will be read by screen readers as a link with no more information available as it uses a HTML entity as the text for the tag so users who can't see the already small icon may be confused as to what it actually is.

This was reported by Gumboots on phpBB.com: Suggested a11y improvement. A solution to this is to use the aria-label attribute with a text string that describes the link. This will let users know what the link is for and what to expect when activating the link.
