(PowerBuilder) JSON Escape and Unescape a String

The encoding mode keyword "json" was added in Chilkat v9.5.0.66 to provide the ability to escape and unescape JSON strings. See Chilkat Encodings for the full list of encoding keywords, such as "base64", "hex", "url", etc.

integer li_rc
oleobject loo_Sb

// Note: This example requires Chilkat version 9.5.0.66 or greater.

loo_Sb = create oleobject
// Use "Chilkat_9_5_0.StringBuilder" for versions of Chilkat < 10.0.0
li_rc = loo_Sb.ConnectToNewObject("Chilkat.StringBuilder")
if li_rc < 0 then
    destroy loo_Sb
    MessageBox("Error","Connecting to COM object failed")
    return
end if

loo_Sb.Append("backslash: \\, A: \u0041")
Write-Debug loo_Sb.GetAsString()

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

// Starting in Chilkat v9.5.0.66, 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.
loo_Sb.Decode("json","utf-8")
Write-Debug loo_Sb.GetAsString()

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

// Now JSON escape the string.
loo_Sb.Encode("json","utf-8")
Write-Debug loo_Sb.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.
