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.
