Twitter now supports are Arabic, Farsi, Hebrew and Urdu. The addition of these languages comes from thirteen thousand volunteers around the world working with the Twitter Translation Center to translate and localize Twitter.com.
Twitter announced that the individuals in that group of thirteen thousand come from diverse backgrounds. There was a Saudi blogger, Egyptian college students, a journalist at the BBC, IT professionals in Iran and Pakistan, an Israeli schoolteacher, the co-founders of the grassroots #LetsTweetInArabic campaign, academics specializing in linguistics, and teenagers in Lebanon.
Twitter says that they are now available in 28 languages from various parts of the world and right to left languages posed a specific problem, especially with tweets that contained both left to right and right to left content. To overcome this problem, Twitter's tech team built special tools to make sure tweets, retweets, hashtags and numbers work in the proper way.
Twitter is available in Traditional Chinese, Indonesian, Portuguese, Italian, Filipino, Finnish, Norwegian, Polish, Turkish, Danish, Malay, English, French, Korean, Swedish, Spanish, Simplified Chinese, Hindi, Japanese, German, Russian and Dutch.
The Twitter Translation Center employs about 4,25,000 volunteers from all over the world. This move of adding right to left language support is critical as the role of Twitter in the Arab Spring is pretty well known and important.
Twitter users in those countries could still tweet in their native languages just by typing in those languages, however, they had to interact with Twitter in a language other than their own. And of course, hashtags weren't supported.
Now, however, Twitter should be easier to use to dispense information and take appropriate action in more place where it is needed.
