What You'll Learn

How to display the reversed E (Ǝ) in HTML using hexadecimal, decimal, and CSS escape methods. In Unicode this is U+018E (LATIN CAPITAL LETTER REVERSED E), a horizontally flipped capital E used in typography and linguistic notation. It sits in the Latin Extended-B block.

Render it with Ǝ, Ǝ, or CSS escape \18E. There is no named HTML entity for this character, so numeric codes or CSS must be used.

🧠 How It Works

1

Hexadecimal Code

&#x018E; uses the Unicode hexadecimal value 018E to display the reversed E. The x prefix indicates hexadecimal format.

HTML markup
2

Decimal HTML Code

&#398; uses the decimal Unicode value 398 to display the same character. A common method for Latin Extended-B characters.

HTML markup
3

CSS Entity

\18E is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.

Same visual result

All three methods produce the glyph: Ǝ. Unicode U+018E sits in Latin Extended-B. Lowercase counterpart: U+0258 (ɘ). There is no named HTML entity. Do not confuse with plain E (U+0045).

Use Cases

The reversed E (Ǝ) is commonly used in:

🎨 Typography

Typographic designs, mirrored lettering, and creative text that uses the reversed capital E form.

🔤 Phonetics

Phonetic and linguistic notation requiring the reversed E glyph.

📚 Linguistics

Language documentation and academic papers on extended Latin characters.

📄 Specialized fonts

Font testing tools and Unicode character showcases for Latin Extended-B.

📝 Academic papers

Scholarly publications referencing reversed E in linguistic notation.

🌐 Internationalization

Content requiring extended Latin glyphs beyond basic ASCII or Latin-1.

🔍 Search & SEO

Correct rendering so specialized linguistic content can be found and indexed.

💡 Best Practices

Do

  • Use &#398; or &#x018E; in HTML (no named entity exists)
  • Serve pages as UTF-8; you can also type Ǝ directly in UTF-8 source
  • Use fonts that support Latin Extended-B (U+0180–U+024F)
  • Distinguish Ǝ (reversed E) from plain E (U+0045) and Ɛ (open E)
  • Pick one numeric style (hex or decimal) per project for consistency

Don’t

  • Assume a named entity exists—there is none for Ǝ
  • Substitute plain E or a rotated character when Ǝ is required
  • Put CSS escape \18E in HTML text nodes
  • Use padded Unicode notation like U+0018E—the correct value is U+018E
  • Use \0018E in CSS—the correct escape is \18E

Key Takeaways

1

Three references render Ǝ (no named entity)

&#x018E; &#398;
2

For CSS stylesheets, use the escape in the content property
