sentences:  For example, the character U+1EBF (ế), used in Vietnamese, has both an acute and a circumflex accent.Its canonical decomposition is the three-character sequence U+0065 (e) U+0302 (circumflex accent) U+0301 (acute accent).The combining classes for the two accents are both 230, thus U+1EBF is not equivalent to U+0065 U+0301 U+0302.
