🧠 How It Works

1

Named Entity

&jcirc; is the standard named entity for ĵ—readable in source HTML and part of the HTML5 entity set.

HTML markup
2

Hexadecimal Code

&#x135; uses the Unicode hexadecimal value 135 to display the character. The x prefix indicates hexadecimal format.

HTML markup
3

Decimal HTML Code

&#309; uses the decimal Unicode value 309 to display the same character. A common method for Latin Extended-A characters.

4

CSS Entity

\135 is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.

=

Same visual result

All four methods produce the glyph: ĵ. Unicode U+0135 sits in Latin Extended-A. It decomposes to j (U+006A) + combining circumflex (U+0302). Uppercase equivalent: U+0134 (&Jcirc;). Do not confuse with plain j or ǰ (j with caron).

💡 Best Practices

Do

  • Use &jcirc; in HTML when possible for readability
  • Serve pages as UTF-8; you can also type ĵ directly in UTF-8 source
  • Set lang="eo" on Esperanto content to aid pronunciation
  • Use fonts that support Latin Extended-A characters
  • Distinguish ĵ (circumflex) from plain j and ǰ (caron)

Don’t

  • Substitute plain j when ĵ is required for correct Esperanto spelling
  • Confuse circumflex ĵ with caron ǰ or other accented j variants
  • Put CSS escape \135 in HTML text nodes
  • Assume all fonts render Latin Extended-A glyphs identically
  • Omit UTF-8 encoding on pages with extended Latin characters
