One year ago I tested all free and commercial Nagari fonts I could find (including all from CDAC distributed at the last World Sanskrit Conference). The result was disappointing. There are hardly any fonts which are without errors of placement as you describe etc. Unfortunately I did not start a catalogue of faults, because I could not really find anyone with who would be able to solve them.

Being no expert on either of the fields I cannot say whether it is a problem of the font or XeTeX or the interaction, but it means, if you have to print a book, there is only one or two that work and look o.k (for Sanskrit), that is, Devanagari Monotype and Sanskrit 2003, which is also fine, but it is really a bold font for verses, not for running text you want to read.

The situation remains quite unsatisfactory for TeX users, but perhaps also for others, which I think is absurd in view of the enormous Indian book market.

I was looking for some free, unicode compliant,
devanagari font family that  has regular, italic and bold variants.  I found
that aksharyogini, CDAC-GISTYogesh, FreeSans and FreeSerif
fit the bill. But, there are different problems with different fonts.
Here is a minimal example with the problems explained with comments.
  Yogesh font is OK but
for the one problem.
Is there a free font with all the three variants that works
properly?
