The Unicode Standard v. 5.1 has 16 precomposed characters with tilde above, viz. ‘A’, ‘a’, ‘O’, ‘o’, ‘N‘ and ‘n‘ in Latin-1 Supplement, ‘I’, ‘i’, ‘U’ and ‘u‘ in Latin Extended-A, and ‘E’, ‘e’, ‘V’, ‘v’, ‘Y’ and ‘y’ in Latin Extended Additional (the latter ten characters are not included in this recommendation). This subrange contains one other precomposed character with tilde. The Unicode Standard advises encoding characters of this type as a sequence of the baseline character and the COMBINING TILDE (0303), and this way of encoding has been given as an alternative below.
