URL encoded	`%C3%B3`

Method 2: Type it directly with UTF-8

ó can also be written as o 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 ó

ó is Unicode U+00F3, named LATIN SMALL LETTER O WITH ACUTE. It is used in Spanish, Portuguese, Italian, Polish, Czech, Slovak, Hungarian and Icelandic. A short line slanting up to the right. It marks stress in Spanish (canción), a closed vowel in French (été), vowel length in Czech, Hungarian and Irish, and a rising tone in Vietnamese and Pinyin. See the ó 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.
