Meta Charset Checker
Score whether the document declares UTF-8 early — not a ranking trick, just decode hygiene.
What this tool gives you
Check meta charset
Fetch a public page or paste the head. This scores document encoding — not a ranking trick.
What this checker looks for
charset tells the browser how to decode bytes. Missing or late UTF-8 turns titles and copy into mojibake.
HTML5 charset
One <meta charset="utf-8"> in <head>, not only Content-Type.
UTF-8 only
Public pages should not ship windows-1252 or ISO-8859-1.
Hyphen spelling
utf-8 is the HTML5 token. utf8 still works, but looks sloppy.
First 1024 bytes
Browsers ignore a late charset after title, CSS or scripts.
One declaration
Do not mix charset= with a second http-equiv Content-Type.
Not a ranking lever
This is decode hygiene, not a citation trick.
How to use the checker
Fix encoding first. Language, viewport and title come after the bytes decode.
Check the live page
Fetch the public URL or paste the <head> from view-source.
Keep UTF-8
charset="utf-8" as the first tag in <head>.
Drop the old http-equiv
HTML5 charset is enough. Do not ship latin-1.
What a healthy charset usually includes
One tag. UTF-8. First in head. Hyphen, not utf8.
| Part | Job | Default for public sites |
|---|---|---|
| meta charset | Declare document encoding | charset="utf-8" |
| HTML5 attribute | Short form in <head> | prefer over http-equiv |
| First 1024 bytes | Browser encoding lock | before title and CSS |
| One declaration | Avoid mixed signals | do not duplicate |
| http-equiv | XHTML leftover | omit if charset is set |
| latin-1 / 1252 | Legacy encodings | never on public pages |

Meta charset FAQs
Does meta charset make ChatGPT cite my page?
No. charset only tells browsers how to decode bytes. Citations still depend on crawl access, answer-ready content and corroboration.
Is http-equiv Content-Type enough?
It works, but HTML5 prefers <meta charset="utf-8"> as the first tag in <head>. Keep one declaration, not both.
Why does charset have to be early?
Browsers lock encoding in the first 1024 bytes. A charset after a long title, CSS or script may be ignored.
