Definition

What Is Uppercase Oe Close Cut?

Uppercase Oe close cut (Œ) is the Unicode character at U+0152 in Latin Extended-A. Official name: LATIN CAPITAL LIGATURE OE — a single capital letter that joins O and E, used in French and related typography.

Remember

Character     Œ
Unicode       U+0152
Named entity  &OElig;  (capital OE)
Hex entity    &#x152;
Decimal       &#338;
CSS escape    \0152
Not the same  œ · ɶ · OE

Prefer &OElig; in HTML markup — the capital OE in the name matters. Numeric forms and typing Œ in UTF-8 also work. For the lowercase letter, use &oelig; (œ).

Try It Yourself

How It Works

1. Named: &OElig; (capital OE) is the clearest HTML form for U+0152. Lowercase &oelig; is a different character (œ).

2. Hex: U+0152 → Œ in HTML. Same glyph as the named entity.

3. Decimal: same code point as 338 → Œ. Same glyph as hex and named.

4. CSS: use \0152 in content (not an HTML entity). #point::after appends that Œ after the paragraph text.

5. Typed / word: paste Œ in UTF-8, or write &OElig;UVRE with lang="fr".

Pitfalls & Tips

Common mistakes when working with U+0152.

Case

&OElig; ≠ &oelig;

&OElig; → Œ (capital). &oelig; → œ (lowercase). Entity names are case-sensitive.

vs OE

Not two ASCII letters

Typing OE is not the same as one precomposed ligature. Prefer &OElig; for French spelling.

vs ɶ

Not the IPA symbol

ɶ is IPA small capital OE. Œ is the French capital ligature — different code points and uses.

vs Ö

Not an umlaut

Ö (Ö) is Ö with two dots. Œ joins O and E into one letter.

Encoding

Keep UTF-8 declared

Latin Extended-A letters display reliably with <meta charset="UTF-8">. Prefer named entities when encoding is uncertain.

CSS vs HTML

Do not mix escapes

\0152 belongs in CSS strings. &OElig; / Œ / Œ belong in HTML.

A11y

Use real language context

When Œ appears in French words, keep surrounding text and lang accurate (for example lang="fr").
