Tate ✍️

Build Status Code Coverage Maintainability Downloaded Gem Version

Tate converts accented characters and transliterates non-latin scripts to their closest ASCII equivalent.

Tate is a productivity tool, it behaves like a standard Unix application and can be chained with other Unix commands. It reads from standard input and writes to standard output. You can use it either as a commandline utility or a library.


Let's say you have a French sentence with a lot of weird characters and you want to convert it into ASCII in the most representative way. You can use:

echo 'Le cœur de la crémiére' | tate  #=> Le coeur de la cremiere

Or some Bulgarian text you can't read:

echo 'Здравей!' | tate --lang=bg  #=> Zdravey!

Set language using lang option for custom filters, e.g. German:

echo 'Von großen Blöcken haut man große Stücke.' | tate --lang=de

Letters ö, ü and ß will be transliterated based on German transliteration rules:

Von grossen Bloecken haut man grosse Stuecke.

Language specific punctuation will be converted to closest ASCII equivalent.

For example, in Catalan, notice how the quotes (cometes franceses) and the interpunct (punt volat) are transliterated:

«Dóna amor que seràs feliç!». Això, il·lús company geniüt, ja és un lluït rètol blavís d’onze kWh.
"Dona amor que seras felic!". Aixo, il-lus company geniut, ja es un lluit retol blavis d'onze kWh.


Add this line to your application's Gemfile:

gem 'tate'

And then execute:

$ bundle

Or install it yourself as:

$ gem install tate


Ruby Library

require 'tate'
Tate::transliterate('Zəfər', language='az')  #=> Zefer

Commandline Utility

tate is short for transliterate.

Nobody has time to type transliterate in the terminal.
