Decode 2-digit Hex Escaped

See more HTML-to-XML/Text Examples

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

require 'chilkat'

# 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..

sb = Chilkat::CkStringBuilder.new()

sb.Append(s)
numReplaced = sb.Replace("\\x","\\u00")

# Now decode from "json" escapes
sb.Decode("json","utf-8")

# Show the decoded string
print sb.getAsString() + "\n";

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