String Escape / Unescape FAQ
Why are there different escapings at all?
Each context has different dangerous characters: quotes break JSON strings, angle brackets break HTML, ampersands break URLs. Escaping is context-armour — using the wrong flavour is how injection bugs are born.
Is escaping the same as sanitising?
No: escaping makes text inert IN a context; sanitising REMOVES dangerous content. Displaying user input wants escaping at output time — this tool is that operation, portable.
