Demonstrates how to replace escaped us-ascii chars such as \x7b and \x22 with the chars. Visual FoxPro

LOCAL s
LOCAL loSb
LOCAL lnNumReplaced

*  We have the following string with some us-ascii chars escaped like this:
s = "\x7b\x22responseContext\x22:\x7b\x22"

*  Note: The above escaping does not conform to any standard format (as far as I know).
*  Chilkat does not have anything to decode from the above.
*  However, we can 1st transform into a standard format, and then decode..

*  JSON escapes chars outside us-ascii like this:  "Hello, \ud83d\ude03!"
*  We can transform the above to this:  "\u007b\u0022responseContext\u0022:\u007b\u0022"
*  And then decode..

loSb = CreateObject('Chilkat.StringBuilder')

loSb.Append(s)
lnNumReplaced = loSb.Replace("\x","\u00")

*  Now decode from "json" escapes
loSb.Decode("json","utf-8")

*  Show the decoded string
? loSb.GetAsString()

*  Here's the result: {"responseContext":{"
