# Declare UTF-8 character encoding

Missing or incorrect charset causes mojibake (garbled text), broken special characters, and security vulnerabilities from character encoding attacks.

## Quick Reference

- Add `<meta charset="UTF-8">` as the first element in <head>
- Must appear within the first 1024 bytes of the document
- UTF-8 supports all languages and special characters

## Check

Verify that this HTML document declares UTF-8 character encoding in the head section and that it's positioned early in the document.
