❓ FAQ
What's the difference between encoding and decoding?
Encoding converts special characters to HTML entities (e.g., < becomes <). Decoding reverses this process.
When should I use "Encode quotes"?
Enable this when encoding HTML attributes to safely escape quote characters (" and ').
What does "Encode non-ASCII" do?
This converts non-ASCII characters (like é, ñ, 中) to numeric HTML entities (é, ñ, 中).
What's the difference between Text and Attribute modes?
Text mode encodes <, >, and &. Attribute mode also encodes quotes for safe HTML attributes.
