As far as I know there are only two solutions:
If you are an end user and want to read Tamil books in your device, you can try to find information how to change the system font of your reader (or you buy another reader, a good one now!)
If you are a vendor, you can hardly expect that all your clients start adapting the firmware. In this case the only thing you can do is give a warning to your customers. Something like: Attention, books in Tamil cannot be read properly on these devices: Sony ... etc.
I think you really need a list of devices here. Telling that readers based on ADE are no good, isn't a solution. Most of your customers probably aren't aware what ADE is. Not everyone is a member of this forum.
Wouldn't you say that was a little strong to say that Tamil cannot be read properly, when the only problem is in metadata. The book can be read fine unless I am missing something. The publisher could say something about the metadata I suppose but that does not detract from reading the book.
