match disregards the diacritics that distinguish these
variants. In addition, @code{a} matches other characters that
resemble it, or have it as part of their graphical representation,
such as U+249C @sc{parenthesized latin small letter a} and U+2100
@sc{account of} (which looks like a small @code{a} over @code{c}).
such as U+00AA @sc{feminine ordinal indicator} and U+24D0
@sc{circled latin small letter a} (which looks like a small @code{a}
inside a circle).
Similarly, the @acronym{ASCII} double-quote character @code{"} matches
all the other variants of double quotes defined by the Unicode
standard. Finally, character folding can make a sequence of one or
more characters match another sequence of a different length: for
example, the sequence of two characters @code{ff} matches U+FB00
@sc{latin small ligature ff}. Character sequences that are not identical,
but match under character folding are known as @dfn{equivalent
character sequences}.
@sc{latin small ligature ff} and the sequence @code{(a)} matches

that are not identical, but match under character folding are known as
@dfn{equivalent character sequences}.
