Unless two characters are canonically equivalent, they are not "duplicate" in the narrow sense. There is, however, room for disagreement on whether two Unicode characters really encode the same [[grapheme]] in cases such as the {{unichar|00B5|MICRO SIGN|nlink=Micro-}} versus {{unichar|03BC|GREEK SMALL LETTER MU |nlink=Mu (letter)}}.

This should be clearly distinguished from Unicode characters that are rendered as identical glyphs or near-identical glyphs ([[homoglyph]]s), either because they are historically cognate (such as Greek [[Η]] vs. Latin [[H]]) or because of coincidental similarity (such as Greek [[Ρ]] vs. Latin [[P]], or Greek Η vs. Cyrillic [[Н]], or the following homoglyph sextupletseptuplet: astronomical symbol for "Sun" [[☉]], "circled dot operator" [[XNOR gate|⊙]], the Gothic letter [[𐍈]], the IPA symbol for a bilabial click {{IPA link|ʘ}}, the Osage letter 𐓃, the Tifinagh letter ⵙ), and the archaic cyrillic letter [[Monocular O|Ꙩ]].)
