Uppercase I with dot above (İ) is the Unicode character at U+0130 in Latin Extended-A. Official name: LATIN CAPITAL LETTER I WITH DOT ABOVE — the Turkish dotted capital I. In Turkish, İ pairs with lowercase i, while plain I pairs with dotless ı.
Remember
Character İ
Unicode U+0130
Named entity İ (capital I)
Hex entity İ
Decimal İ
CSS escape \0130
Not the same I · ı · Î
Prefer İ in HTML markup. Numeric forms and typing İ in UTF-8 also work. For Turkish text, use lang="tr" so casing and pronunciation context are clear.
Using Named Entity: İ
Using Hex Code: İ
Using HTML Code: İ
Using CSS Entity: İ
Typed directly: İ
Word: İSTANBUL
How It Works
1. Named:İ (capital I) is the clearest HTML form for U+0130.
2. Hex:U+0130 → İ in HTML. Same glyph as the named entity.
3. Decimal: same code point as 304 → İ. Same glyph as hex and named.
4. CSS: use \0130 in content (not an HTML entity). #point::after appends that İ after the paragraph text.
5. Typed / word: paste İ in UTF-8, or build Turkish words like İSTANBUL with lang="tr".
Pitfalls & Tips
Common mistakes when working with U+0130.
Turkish
İ/i and I/ı are different pairs
In Turkish, dotted İ uppercases from i, and plain I uppercases from dotless ı. Do not treat them as one letter.
vs I
Not plain Latin I
ASCII I (U+0049) has no combining-style dotted capital form. For Turkish titles that need İ, use İ.
vs ı
Not the lowercase partner of İ
Dotless ı pairs with plain I. The lowercase partner of İ is ordinary i.
CSS
text-transform can surprise you
Browser text-transform: uppercase may not apply Turkish rules unless language is set correctly. Prefer writing İ explicitly when you need it.
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
\0130 belongs in CSS strings. İ / İ / İ belong in HTML.
Compatibility

Bottom line: Prefer İ in HTML. Use \\0130 only inside CSS content. Remember Turkish pairs: İ/i and I/ı.

Key Takeaways
Unicode: uppercase I with dot above is U+0130 (decimal 304) — glyph İ.
HTML: prefer İ — also İ / İ.
CSS: use \0130 inside content for generated text.
Meaning:İ is Turkish dotted capital I — not plain I, not ı (dotless).
Use İ (named), İ (hex), İ (decimal), type İ directly in UTF-8, or the CSS escape \0130 in content. Prefer İ in normal HTML.
U+0130 (LATIN CAPITAL LETTER I WITH DOT ABOVE). Hex 130, decimal 304. It belongs to Latin Extended-A (U+0100–U+017F).
Yes. Use İ (capital I). Numeric forms İ and İ also work.
No. İ is the Turkish dotted capital I (U+0130). Plain I is U+0049. Dotless lowercase ı is U+0131 (ı).
Use it for Turkish (and related) text that needs İ — for example titles and uppercase forms of words spelled with dotted i. Do not use plain I when Turkish casing requires İ.
HTML entities (İ, İ, or İ) go in markup. The CSS escape \0130 goes in stylesheet strings (usually content on ::before/::after).
