(Visual FoxPro) StringBuilder to Bytes (in BinData)

Demonstrates converting a string to bytes of a particular character encoding.

Note: This example requires Chilkat v9.5.0.64 or later.

* This initial step gets string data to be used in this example from a live URL.
* It assumes Chilkat HTTP API to have been previously unlocked.
* See Global Unlock Sample for sample code.

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Http')
loHttp = CreateObject('Chilkat.Http')
loHttp.VerboseLogging = 1
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbJson = CreateObject('Chilkat.StringBuilder')
lnSuccess = loHttp.QuickGetSb("https://www.chilkatsoft.com/exampleData/greekAlphabet.json",loSbJson)
IF (NOT lnSuccess) THEN
    ? loHttp.LastErrorText
    RELEASE loHttp
    RELEASE loSbJson
    CANCEL

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbGreek = CreateObject('Chilkat.StringBuilder')
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJson = CreateObject('Chilkat.JsonObject')
loJson.LoadSb(loSbJson)

* The JSON contains this:

* 	{ 
* 	  "greekAlphabet": "Α α Β β Γ γ Δ δ Ε ε Ζ ζ Η η Θ θ Ι ι Κ κ Λ λ Μ μ Ν ν Ξ ξ Ο ο Π π Ρ ρ Σ σ ς Τ τ Υ υ Φ φ Χ χ Ψ ψ Ω ω"
* 	} 

lcGreekAlphabet = loJson.StringOf("greekAlphabet")
loSbGreek.Append(lcGreekAlphabet)

* Append the Windows-1253 represention of the string..
* In this encoding, each Greek char is one byte per char.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.BinData')
loBinWindows1253 = CreateObject('Chilkat.BinData')
loBinWindows1253.AppendSb(loSbGreek,"windows-1253")
* Save to a Windows-1253 text file:
loBinWindows1253.WriteFile("qa_output/greek_win1253.txt")

* Show the bytes in the quoted-printable format so we can easily see the Windows-1253 byte values.
? loBinWindows1253.GetEncoded("qp")

* The result is shown here:

* Append the utf-8 represention of the string..
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.BinData')
loBinUtf8 = CreateObject('Chilkat.BinData')
loBinUtf8.AppendBom("utf-8")
loBinUtf8.AppendSb(loSbGreek,"utf-8")
* Save to a utf-8 text file:
loBinUtf8.WriteFile("qa_output/greek_utf8.txt")
* Show the bytes in the quoted-printable format so we can easily see the utf-8 char representations.
