Typing ũ (u with tilde) on HTML takes a few seconds once you know the trick. The short answer is ũ. Read on for step-by-step instructions, the uppercase Ũ and what to do when a method does not work.

ũ on HTML: ũ

Ũ on HTML: Ũ

Or copy it:

Method 1: Codes for web pages

Format	Code for ũ
Decimal entity	`ũ`
Hex entity	`ũ`
CSS content	`content: "\0169";`
JavaScript	`"\u0169"`
URL encoded	`%C5%A9`
UTF-8 bytes	`C5 A9`

Method 2: Type it directly with UTF-8

If your page starts with <meta charset="utf-8"> and the file is saved as UTF-8, you can paste ũ straight into the HTML. Entities are only needed when your editor or database cannot store the character.

Method 3: Watch for normalization

ũ can also be written as u plus a combining mark. Both look the same but compare as different strings. In JavaScript, call str.normalize("NFC") before comparing or searching.

About the letter ũ

ũ is Unicode U+0169, named LATIN SMALL LETTER U WITH TILDE. It is used in Vietnamese. A wavy line above a letter. Spanish uses it for ñ, Portuguese for nasal vowels (ã, õ), Estonian for õ, and Vietnamese for the broken rising tone. See the ũ character page for every code and shortcut.

Troubleshooting

If you see Ã and other symbols, the file is UTF-8 but the browser reads it as Windows-1252. Add the meta charset tag.
Named entities are case sensitive: É and é are different letters.
In XML and XHTML only five named entities exist, so use numeric codes there.
