How It Works
1. Hex / decimal:U+00DE → Þ or Þ in HTML.
2. Named:Þ is the readable HTML5 alias for the same code point (name is case-sensitive).
3. CSS: use \00DE in content (not an HTML entity). #point::after appends that glyph after the paragraph text.
4. Language sample:lang="is" marks Icelandic context; words like Þú and Þetta use capital thorn.
Pitfalls & Tips
Common mistakes when working with this character.
Named
Prefer Þ
The named entity is easier to read than numeric forms. Keep the trailing semicolon; the name is uppercase.
Look-alikes
Not eth or P
U+00DE is thorn (Þ). Do not confuse with eth Ð (Ð, U+00D0) or plain P (U+0050).
Case
Use the correct case pair
Lowercase is þ (U+00FE). Named entities are case-sensitive: Þ ≠ þ.
Sound
Voiceless th
In Icelandic, thorn typically represents a voiceless dental fricative (like English think), while eth often represents the voiced counterpart.
CSS vs HTML
Do not mix escapes
\00DE belongs in CSS. Named/numeric entities belong in HTML.
Semicolon
End references
Always finish with ; — write Þ, not Þ.
