Frequently Asked Questions
Why do I need to escape strings?
Unescaped special characters (quotes, backslashes, newlines) break string literals in code. Escaping ensures the string is interpreted correctly by the parser. It also prevents injection attacks in HTML (XSS) and database queries (SQL injection).
Does it handle unicode?
Yes, unicode is properly escaped.
What characters need escaping in different contexts?
JavaScript strings: double quotes, single quotes, backslashes, newlines ( ), tabs ( ). JSON: double quotes, backslashes, control characters. HTML: < > & " ' (use < > & " '). Regular expressions: . ^ $ * + ? ( ) [ ] { } | \. Each context has its own set of special characters that must be escaped to be treated as literal text.
