Use Cases

• Embedding user-supplied text safely

  Escape reserved characters in comments, names, or form input before inserting them into a page template to avoid breaking the markup.

• Preparing code samples for documentation

  Encode angle brackets and ampersands in a code snippet so it displays literally inside an HTML-based doc site or blog post.

• Producing ASCII-safe output

  Convert accented characters and emoji to numeric entities when a system or feed only accepts pure ASCII content.

• Sanitizing text before templating

  Pre-encode dynamic strings before pasting them into an email template or static HTML file to reduce the risk of broken layout.

Examples

<a href="/x">Fish & Chips</a>

<a href="/x">Fish & Chips</a>

Benefits

• ✓Prevent dynamic text from breaking your HTML layout
• ✓Reduce the risk of markup injection when embedding content
• ✓No account or upload required

Best Practices

• Encode untrusted or user-supplied text before inserting it into a page.
• Use encode-all mode when your output must stay pure ASCII.

Common Mistakes

• Encoding the ampersand after other characters, causing double-encoding.
• Relying on encoding alone for security instead of proper context-aware templating.
