The prompt for Cursor

Copy and paste this into your Cursor chat exactly as-is.

Apply these changes to my codebase. Edit the files directly and keep existing formatting:

Add charset declaration

1. Add <meta charset="utf-8"> as the first element in <head>.

Why this matters

UTF-8 is the one charset everyone supports. Declaring it explicitly prevents browsers from guessing — and the guess is sometimes wrong, especially for legacy setups.

AI-generated HTML templates include this by default, but some micro-edits can drop it. A quick check avoids the dreaded "�" symbols across your content.

Common mistakes to avoid

error_outlinePutting the charset meta after the title — browsers may re-parse the head when they discover it, slowing paint.
error_outlineUsing `iso-8859-1` on modern sites — obsolete, breaks emoji and non-Latin characters.
error_outlineRelying on HTTP header only — in-HTML declaration is a safety net.

How to verify the fix worked

check_circleView source — `<meta charset="utf-8">` is the first element in <head>.
check_circleLighthouse → SEO → "Document has a meta charset" passes.
check_circleCheck content with umlauts, accents, and emojis — all render correctly.

Frequently asked questions

Uppercase UTF-8 vs lowercase utf-8?expand_more

Either works. Lowercase is common convention.

Is HTTP charset header enough?expand_more

Works in most cases, but the in-HTML meta is a safety net for when headers are stripped (e.g., local file viewing).
