I have been using the Sanskrit 2003 unicode Devanagari font for some time, and have noticed that for some characters, the anusvāra almost merges with characters like sign for short "i".  Here are a few sample lines:

     Am I alone in seeing these problems, or is this happening only on Mac computers, and not on Windows?  I have written to Omkarananda Ashram about this and I am hoping to hear from them.

    If someone has a solution to this font problem, I would appreciate hearing it.
