When an ⟨n⟩ or ⟨m⟩ followed a vowel, it was often omitted, and a tilde (physically, a small ⟨N⟩) was placed over the preceding vowel to indicate the missing letter; this is the origin of the use of tilde to indicate nasalization (compare the development of the umlaut as an abbreviation of ⟨e⟩.) This avoided a shape definition error in the Unicode code charts: the wave dash reference glyph in JIS / Shift JIS[22][23] matches the Unicode reference glyph for U+FF5E,[24] while the reference glyph for U+301C[25] was reflected, incorrectly,[26] when Unicode imported the JIS wave dash.

The JIS / Shift JIS wave dash is still formally mapped to U+301C as of JIS X 0213,[34] whereas the WHATWG Encoding Standard used by HTML5 follows Microsoft in mapping 0x8160 to U+FF5E. A triple tilde (≋) is often used to show congruence, an equivalence relation in geometry. Circa uguale latex. In practice the full-width tilde (全角チルダ, zenkaku chiruda), Unicode U+FF5E, is often used instead of the wave dash (波ダッシュ, nami dasshu), Unicode U+301C, because the Shift JIS code for the wave dash, 0x8160, which is supposed to be mapped to U+301C,[19][20] is instead mapped to U+FF5E[21] in Windows code page 932 (Microsoft's code page for Japanese), a widely used extension of Shift JIS. : /~bill). [35] These two code points have a similar or identical glyph in several fonts, reducing the confusion and incompatibility. Nello spagnolo si chiama tilde anche l'accento grafico delle parole, avente sempre la forma dell'accento acuto italiano (´) – come in perché.
