Definition

What Is Uppercase U Ogonek?

Uppercase U ogonek (Ų) is the Unicode character at U+0172 in Latin Extended-A. Official name: LATIN CAPITAL LETTER U WITH OGONEK — a capital U with a small hook (ogonek) below the right stem, used especially in Lithuanian.

Remember

Character     Ų
Unicode       U+0172
Named entity  &Uogon;  (capital U)
Hex entity    &#x172;
Decimal       &#370;
CSS escape    \0172
Not the same  ų · Ū · U

Prefer &Uogon; in HTML markup — the capital U in the name matters. Numeric forms and typing Ų in UTF-8 also work. For the lowercase letter, use &uogon; (ų).

Try It Yourself

How It Works

1. Named: &Uogon; (capital U) is the clearest HTML form for U+0172. Lowercase &uogon; is a different character (ų).

2. Hex: U+0172 → Ų in HTML. Same glyph as the named entity.

3. Decimal: same code point as 370 → Ų. Same glyph as hex and named.

4. CSS: use \0172 in content (not an HTML entity). #point::after appends that Ų after the paragraph text.

5. Typed / word: paste Ų in UTF-8, or build Lithuanian forms like GAL&Uogon; with lang="lt".

Pitfalls & Tips

Common mistakes when working with U+0172.

Case

&Uogon; ≠ &uogon;

&Uogon; → Ų (capital). &uogon; → ų (lowercase). Entity names are case-sensitive.

vs Ū

Not a macron

Ū (&Umacr;) has a bar above. Ų has an ogonek (hook) below — different marks.

vs U

Not plain capital U

Keyboard U is U+0055. Use U+0172 only when you need the ogonek form.

Encoding

Keep UTF-8 declared

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

CSS vs HTML

Do not mix escapes

\0172 belongs in CSS strings. &Uogon; / Ų / Ų belong in HTML.

A11y

Use real language context

When Ų appears in Lithuanian words, keep surrounding text and lang accurate (for example lt) so screen readers get useful context.
