+@item paired-bracket
+Corresponds to the Unicode @code{Bidi_Paired_Bracket} property.  The
+value of this property is the codepoint of a character's @dfn{paired
+bracket}, or @code{nil} if the character is not a bracket character.
+This establishes a mapping between characters that are treated as
+bracket pairs by the Unicode Bidirectional Algorithm; Emacs uses this
+property when it decides how to reorder for display parentheses,
+braces, and other similar characters (@pxref{Bidirectional Display}).

+@item bracket-type
+Corresponds to the Unicode @code{Bidi_Paired_Bracket_Type} property.
+For characters whose @code{paired-bracket} property is non-@code{nil},
+the value of this property is a symbol, either @code{o} (for opening
+bracket characters) or @code{c} (for closing bracket characters).  For
+characters whose @code{paired-bracket} property is @code{nil}, the
+value is the symbol @code{n} (None).  Like @code{paired-bracket}, this
+property is used for bidirectional display.
