Now-a-days, lots and lots of Telugu content (both online and offline) is being created in Unicode. There are many free typing tools for Telugu (even, on mobile phones too). People no longer need to buy proprietary fonts and text editors to compose in Telugu. And, a good number of beautiful Telugu Unicode fonts are available for free download, thanks to Telugu Vijayam project of earlier joint Andhra Pradesh government. (These Telugu fonts are also available in Google Fonts.)
Modern publishing tools such as Adobe InDesign have support for Unicode Telugu. And, many people have already published their books in Unicode.
Despite that, most of the Telugu publishing and printing industry and small DTP operators have not yet moved to Unicode. (We need to create awareness of Unicode and its benefits for Telugu content and publishing industry.)
Because the Telugu publishing industry and media still using proprietary fonts, people are looking for tools to convert Unicode text into Anu and other proprietary Telugu fonts for printing.
Here are a couple of links that try to convert Unicode Telugu text to Anu fonts:
There are just experiments and may not server real world uses efficiently (like converting the whole book). I’ve learned that Purushoth Kumar (of EMESCO Books) has developed a offline converter that can convert to many proprietary formats (Anu, baraha, etc). He is ready to offer his offline converter for a small price (or even for free, if you ask him nicely). You can contact him at 98488 90802.
I hope this post will become obsolete sooner and all of Telugu publishing and printing happens with Unicode.
