The dotted circle in the Unicode tables means that this is a combining
mark - specifically, in this case, that the glyph will appear to the
left of the preceding glyph that it is composed with.
To get the behavior I assume you want, you should enter U+0BC7 after the
others, i.e.:
0B95 0BCD 0BB7 0BC7, for this result: க்ஷே
= க + ் + ஷ + ே
Note that this may not appear correctly in some terminals when you run
text-mode Emacs - it doesn't in mine.

The Unicode standard provides information on how Indic scripts should be
rendered. Version 1.0 is available at the link below; I don't know if
any later version exists.
http://www.unicode.org/versions/Unicode1.0.0/V2appA.pdf
The dotted circle is generally used in charts to illustrate where a
combining character would be placed relative to preceding characters,
and in rendering to show an ill-formed sequence (i.e. the preceding
consonant cluster is missing).

I am not sure what layer is responsible for doing this rendering, so I
don't know if there's anything you need to do or can do at the font level.
