Example: Capital open E Ɛ
Case pair: Ɛ / ɛ
How It Works
1. Hex:U+0190 → Ɛ in HTML. The browser turns it into Ɛ.
2. Decimal: same code point as 400 → Ɛ. Same result as hex.
3. CSS: use \0190 in content (not an HTML entity). #point::after appends that Ɛ after the paragraph text.
4. Typed / pair: paste Ɛ in UTF-8, and use ɛ (U+025B) for the small / IPA open e.
Pitfalls & Tips
Common mistakes when working with capital open E.
Named?
No named entity
HTML5 does not define a named entity for U+0190. Use Ɛ or Ɛ.
vs ɛ
Not the small open e
ɛ (U+025B) is the IPA / small open e. Use U+0190 only when you need the capital form.
vs E
Not plain capital E
Keyboard E is U+0045. Use U+0190 only when the open-E capital shape is required.
vs Ǝ
Not reversed E
Ǝ (U+018E) is a horizontally flipped capital E. Open E (Ɛ) is a different letter shape.
CSS vs HTML
Do not mix escapes
\0190 belongs in CSS strings. Ɛ / Ɛ belong in HTML.
