translighterate = transliterate + highlight

(Created after getting no responses to this Stack Overflow question.)

This is a version of Rails's highlight that is transliteration aware.

For example, highlighting 'duss' in 'Düsseldorf' will actually match something:

irb(main):001:0> require 'translighterate'
=> true
irb(main):002:0> Translighterate.highlight("Düsseldorf", "duss")
=> "<mark>Düss</mark>eldorf"

as opposed to this behavior with Rails's highlight:

irb(main):002:0> require 'action_view'
=> true
irb(main):004:0> include ActionView::Helpers::TextHelper
=> Object
irb(main):005:0> highlight("Düsseldorf", "duss")
=> "Düsseldorf"

Add this line to your application's Gemfile:

gem 'translighterate'

And then execute:

$ bundle

Or install it yourself as:

$ gem install translighterate

We have one class Translighterate with one method highlight.

irb(main):001:0> require 'translighterate'
=> true
irb(main):002:0> Translighterate.highlight("Düsseldorf", "duss")
=> "<mark>Düss</mark>eldorf"
