How It Works
1. Named:" is the preferred HTML5 entity for U+0022 — especially useful inside attributes.
2. Hex:U+0022 → " in HTML. Same glyph as the named form.
3. Decimal: same code point as 34 → ".
4. Direct: type " in a UTF-8 body text node. Inside double-quoted attributes, escape with ".
5. CSS: use padded \0022 in content so a following digit is not absorbed into the escape.
Pitfalls & Tips
Common mistakes when working with this punctuation entity.
Attributes
Escape quotes in attributes
Inside attr="…", a literal " ends the value. Use " or switch to single-quoted attributes.
Curly
Straight ≠ curly
" is ASCII ". Typographic quotes are “ / ”. Do not mix them in code or URLs.
Code
Keep straight quotes in code
Smart-quote substitution can break JavaScript, JSON, and HTML attributes. Prefer U+0022 in source code.
CSS pad
Prefer \0022
Short escapes like \22 can swallow the next hex digit. Pad to four digits: \0022.
CSS vs HTML
Do not mix escapes
\0022 belongs in CSS. " / " belong in HTML.
UTF-8
Declare charset
If you paste quotes directly, serve the page as UTF-8 with <meta charset="UTF-8">.
