seo/charset · Character encoding

The page should declare a character encoding with <meta charset>.

Severity: warning

What it checks

Flags a rendered page with no <meta charset> declaration.

Why it matters

Without a declared character encoding the browser must guess, which can render text as mojibake. <meta charset="utf-8"> is the standard, unambiguous declaration and should be the first thing in <head>.

How to fix

<head>
  <meta charset="utf-8" />
  %sveltekit.head%
</head>

Mode differences

Rendered analysis only (the Vite plugin’s build pass, a route you visit in the dashboard). The tag lives in src/app.html, which source analysis (the CLI, the dashboard’s static baseline) does not resolve, so that pass reports nothing for this rule.

Disabling

Record existing findings in the suppressions file (npx svelte-vitals --update-suppressions), scope the rule per route or path with overrides, or turn it off:

export default {
  rules: {
    'seo/charset': 'off'
  }
};
