STRING ESCAPE MATRIX & UNESCAPER

Multi-dialect string codec. Bidirectionally encode or decode escape sequences across JavaScript/JSON string literals (\n, \t, \"), HTML markup entities (&, <), SQL query parameters, and regex metacharacters.

DIALECT:

          Technical specifications for JSON/ECMAScript backslash escapes, XML/HTML character references, SQL string literals, and client privacy.
        

      


      

        
1. Lexical Escape Dialects

        

          Different runtime environments use distinct syntaxes to represent control codes, quote boundaries, and non-printable characters:
        

        
    
          
  • JSON & ECMAScript: Uses the reverse solidus (\). Standard escapes include newline (\n), carriage return (\r), horizontal tab (\t), escaped quotes (\"), and hexadecimal unicode points (\uXXXX).
    • 
          
  • HTML Entities: Employs ampersand-terminated entity names or codepoints to prevent Cross-Site Scripting (XSS) and parser corruption. Core entities: &, <, >, ", and '.
    • 
          
  • SQL Literal Quotes: Under standard ANSI SQL, a single quote (') inside a string literal is escaped by doubling it (''). MySQL and PostgreSQL also support backslash escaping depending on standard compliance mode.

          1. Airgapped Safety
          Executed 100% locally in browser memory. Sensitive code snippets, API keys, or SQL statements never touch a remote server.
        

        

          2. Lossless Unicode
          Correctly parses high and low surrogate pairs and 4-byte UTF-16 surrogate pairs without string truncation.
        

        

          3. Instant Swap
          One-click bidirectional reversal lets you verify decoding accuracy immediately against original source strings.
