Twitter is now available in languages written right-to-left, including Arabic, Farsi, Hebrew and Urdu.

Work began earlier this year via their Translation Center, which crowd-sources translations to make Twitter available to people around the world. Almost half a million people contribute to the Center, and have so far made 28 languages available.

Around 13,000 volunteers worked on the project to make right-to-left language available. Twitter had to create new tools to ensure Tweets, retweets and hashtags work properly for users who may send tweets with both right-to-left and left-to-right content.
