JSON Escape and Unescape a String

Demonstrates how to JSON escape or unescape a string. Lianja

loSb = createobject("CkStringBuilder")

loSb.Append("backslash: \\\\, A: \\u0041")
? loSb.GetAsString()

// The output is:
//    backslash: \\, A: \u0041

// The keyword "json" can be used
// to escape and unescape.  To escape is to encode.  To unescape is to decode.

// Unescape (decode) the string in sb.
loSb.Decode("json","utf-8")
? loSb.GetAsString()

// After JSON unescaping:
//    backslash: \, A: A

// Now JSON escape the string.
loSb.Encode("json","utf-8")
? loSb.GetAsString()

// After JSON escaping:
//    backslash: \\, A: A

// Note: The "A" is not escaped to "\u0041" because there is no need.
// The "\uXXXX" format would be produced for non-printable control chars.
