ascii_folding is a Ruby gem providing functionality for ASCII folding. This gem converts non-ASCII characters in a string to their ASCII approximations based on predefined mappings, making it useful for applications requiring standard ASCII characters, such as slug generation or text normalization.

Install the gem and add to the application's Gemfile by executing:

$ bundle add ascii_folding

If bundler is not being used to manage dependencies, install the gem by executing:

$ gem install ascii_folding

To use the ASCII folding functionality, require the gem in your Ruby script and call the fold method with the string you want to process:

require 'ascii_folding'

input_string = "Your string with special characters like À, É, etc."
ascii_folded_string = AsciiFolding.fold(input_string)
puts ascii_folded_string
