TLDR

Opt for the HTML5 standard **<meta charset="utf-8">** for specifying the character encoding as UTF-8. Choose the simpler over the verbose and outdated **<meta http-equiv="Content-Type" content="text/html; charset=utf-8">**.

<!-- This is how we do it in 2022 --> <meta charset="utf-8">

This brings you the dual advantage of compatibility and ease in modern web development.

The importance of correct encoding

The selection of correct character encoding can significantly affect the interpretation of your content in web browsers. Incorrect encoding can lead to alien ("alien" meaning alien, nothing to do with Area 51 😉) or unreadable characters, potential data corruption, and security vulnerabilities.

Why UTF-8 is a winner

UTF-8, the Unicode-compliant encoding king, supports a vast range of characters. Being a universal choice, it caters to almost all languages and is renowned for its efficiency and glorious flexibility.

HTML5 way of declaring encoding

HTML5 simplifies the encoding declaration to a single succinct line: <meta charset="utf-8">, sparing our featherweight fingers from the verbose and outdated <meta http-equiv="Content-Type">. More code doesn't always mean more power. Remember: A keyboard warrior is known for precision strikes, not mindless thrashing!

Watch out for server settings

Server-side HTTP headers have the ultimate say over your cute <meta> tags. Make sure your server configurations uphold the gavel of justice and align with UTF-8.

Handling the Byte Order Mark (BOM)

When breathing life into your HTML dinosaur (ancient, but still iconic!), remember to save your files as UTF-8 without BOM. Tools like Notepad++ or BBEdit/TextWrangler can help to steer clear of that BOM iceberg. Don't get Titanic'd!

Encoding best practices

To ensure precision and quality while dealing with UTF-8:

  • Be consistent in using UTF-8 across all files and databases.
  • Prefer direct input of characters over HTML entities for improved readability.
  • Validate your encoding with echo and nc commands, like a security guard checking ID at the club.
  • Strive for precision in punctuation: a well-placed comma can be the difference between "Let's eat, grandma!" and "Let's eat grandma!". Hint: The latter might get you into trouble with the law.

Key details about encoding and HTTP

Browsers run the detective's magnifying glass over the first 512 bytes of your document. Make sure your <meta charset="utf-8"> tag paid for front-row seats!

For those HTML creators handling locally stored files or crafting with relative paths, slap in a <base> tag, the GPS of your HTML, to anchor your relative URLs.
