## Overview
The `dummy?` property of an encoding in Ruby returns true if an encoding is a dummy. An encoding is a dummy if the character handling is not properly implemented.

## Syntax
```ruby
Encoding::encoding.dummy?
```
## Return value
A Boolean value is returned. If the encoding is dummy, `true` is returned. Otherwise, `false` is returned. 
## Code 


# check for some dummy encodings
puts "#{Encoding::UTF_8.dummy?}"        # false
puts "#{Encoding::UTF_7.dummy?}"        # true
puts "#{Encoding::UTF_16.dummy?}"       # true
puts "#{Encoding::ISO_8859_1.dummy?}"   # false
puts "#{Encoding::Windows_1250.dummy?}" # false

## Explanation
* Line 2-6: We check if some encodings are dummies using the `dummy?` property of an encoding instance. Then, we print the result to the console.

What is the `dummy?` property for an encoding in Ruby?

The dummy? property in Ruby checks if an encoding is non-functional, returning true if so, false otherwise.
