Definition

What Is the Uppercase C Entity?

Uppercase C (C) is the Basic Latin character at Unicode U+0043 (LATIN CAPITAL LETTER C). You can type C directly in HTML, or write it with a numeric character reference when you need an explicit entity form.

Remember

Character     C
Unicode       U+0043
Hex entity    &#x43;
Decimal       &#67;
CSS escape    \0043
Named entity  (none)
Official name LATIN CAPITAL LETTER C

All of these produce the same glyph: C. Related: Uppercase C Acute (U+0106) and Lowercase C (U+0063).

    }

</body>
</html>

Try It Yourself

How It Works

1. Hex / decimal: U+0043 → C or C in HTML.

2. Direct: typing C in a UTF-8 file is the simplest and preferred approach.

3. CSS: use \0043 in content (not an HTML entity). The four-digit form avoids ambiguity with following hex digits.

4. Sentence: shows ordinary text use — no entity required for everyday letters.

Pitfalls & Tips

Common mistakes when working with this character.

Prefer

Type C directly

For normal text, typing C is clearer than an entity. Use numeric forms only when you need them.

Named?

No named entity

HTML5 does not define a named entity for U+0043. Use C, C, or type C.

Look-alikes

Not C acute or copyright

U+0043 is plain C. U+0106 is Ć. U+00A9 is ©. Do not swap them.

CSS

Prefer a four-digit escape

Use \0043 (not bare \43) so a following digit is not absorbed into the escape.

Case

Uppercase vs lowercase

Lowercase is U+0063 (c / c). Case folding is a separate concern from entities.

Semicolon

End references

Always finish with ; — write C, not &#67.
