Hindi font not display in htc_salsa_C510e_android2.0.3?
See my answer and my comment about replacing a font file Droidsansfallback.ttf. I am sure you can search and find many file sharing sites sharing this file. You can also extract the font file from any of the Android device that you may have.

After replacing the font file and restarting the phone, chances are pretty high that you might not be able to see the word हिन्दी as you see here, rather you might see it split as ह ि न्द ी without spaces. Nothing much you can do if it shows up like this as I my question is all about that :(
