Frequently asked questions
Which characters must be HTML-encoded?
<, >, &, " and ' must be encoded to prevent HTML injection and XSS vulnerabilities.
What is the difference between < and <?
They both produce '<'. Named entities (<) are more readable; numeric entities (<) work in all parsers.
Should I encode all characters?
For security, encode at least <, >, &, " and '. Full encoding is optional but ensures maximum compatibility.
