When to use it

Õ writes U+00D5 (Capital O with Tilde), a capital letter from the Unicode Latin-1 Supplement block, encoded since Unicode 1.1. On a page saved as UTF-8 the letter can simply be typed; the entity helps in ASCII-only templates and code samples.

The name dates from HTML 4, so it works in every browser and in old email clients.

Browsers also accept the legacy form &Otilde without a semicolon, for compatibility with old pages; new HTML should always end the reference with a semicolon.
