Latin Capital A with Tilde Ã

The Latin Capital A with Tilde character (Ã) is a standard HTML entity defined in the HTML specification. In HTML source code, it can be written using the named entity reference Ã, the decimal numeric character reference Ã, or the hexadecimal numeric reference Ã. The character is assigned Unicode code point U+00C3 in the Universal Character Set.

The capital A with tilde (Ã) is primarily used in Portuguese and Vietnamese. In Portuguese, the tilde indicates nasal vowel pronunciation and is essential for correct spelling of many common words. It also appears in the name São Paulo and the country name São Tomé.

Latin extended character entities provide the accented and modified letters required by dozens of European languages. From French accents aigus and graves to German umlauts, Scandinavian rings, and Icelandic thorns, these entities ensure correct rendering of non-ASCII characters within HTML documents. While modern UTF-8 encoded pages can include these characters directly in source code, HTML entities remain valuable for source code clarity and legacy compatibility.

When deciding how to encode the Latin Capital A with Tilde character in your HTML documents, the named entity à is generally the most readable choice for developers reviewing or maintaining source code. The decimal form à and hexadecimal form à are equally valid alternatives that work in contexts where named entities may not be supported, or when generating HTML output programmatically from server-side code. All three representations produce identical visual output in every modern web browser.

Use this entity in Portuguese text (Ã is very common in Brazilian and European Portuguese), Vietnamese, and Guarani. Omitting the tilde in Portuguese changes pronunciation and meaning. It is critical for place names like São Paulo and personal names.
