Uppercase I with double grave (Ȉ) is the Unicode character at U+0208 in Latin Extended-B. Official name: LATIN CAPITAL LETTER I WITH DOUBLE GRAVE — a capital I with two grave marks, used in Slavic linguistics and phonetic transcription.
Remember
Character Ȉ
Unicode U+0208
Named entity (none)
Hex entity Ȉ
Decimal Ȉ
CSS escape \0208
Not the same ȉ · Ì · Ȋ
Prefer Ȉ or Ȉ in HTML markup. You can also type Ȉ in UTF-8. The lowercase pair is ȉ (U+0209). HTML5 has no named entity for either form.
Using Hex Code: Ȉ
Using HTML Code: Ȉ
Using CSS Entity: Ȉ
Typed directly: Ȉ
Case pair: Ȉ / ȉ
How It Works
1. Hex:U+0208 → Ȉ in HTML. Preferred numeric form when you need an entity.
2. Decimal: same code point as 520 → Ȉ. Same glyph as hex.
3. CSS: use \0208 (four hex digits) in content. Shorter forms can be misread by the CSS parser. #point::after appends that Ȉ.
4. Typed / pair: paste Ȉ in UTF-8, or show both cases with Ȉ / ȉ.
5. No named entity: HTML5 does not define a name for U+0208 — use numeric references or type the character. Ì is single-grave Ì, not Ȉ.
Pitfalls & Tips
Common mistakes when working with U+0208.
vs Ì
Not a single grave
Ì (Ì) has one grave mark. Ȉ has two — do not use Ì for double-grave notation.
Named
No named HTML entity
There is no named entity for U+0208. Use Ȉ or Ȉ.
CSS
Use four hex digits
Write \0208, not a short form that a following letter might swallow. Pad to four digits for safety.
Fonts
Needs Extended-B coverage
Some UI fonts omit Latin Extended-B. Prefer a stack that includes Extended-B if the glyph must always show.
CSS vs HTML
Do not mix escapes
\0208 belongs in CSS strings. Ȉ / Ȉ belong in HTML.
Encoding
Keep UTF-8 declared
Extended-B letters display reliably with <meta charset="UTF-8">. Prefer numeric entities when the source file encoding is uncertain.
