Since not all combining sequences have a precomposed equivalent (the last one in the previous example can only be reduced to U+00E9 U+0302), even the normal form NFC is affected by combining characters' behavior.
S obzirom da nemaju svi kombinovani nizovi izmenjeni ekvivalent, (poslednji u prethodnom primeru može biti skraćen samo na U+00E9 U+0302), čak je i normalni oblik NFC pogodjen ponašanjem kombinovanih karaktera.
