On windows, you can run "charmap". It'll display all the characters a given
font contains, and can break it down by unicode subrange. Err... poking around
in charmap hasn't been all that helpful. What unicode values are we talking
about here? Ah! It's all in the Latin subrange, believe it or not. ệ for
example is U+1ec7. So subranges aren't going to help all that much.
That particular character IS in the "Arial" on my system, as are a variety of
other "double diacritic" letters. U+1E00 through U+1EF9, with just a few
charaters missing. I'm using Windows 7, so your results may vary. My XP box's
Arial only has U+1E80 through U+1EF9... which could explain the issue you're
having.
In particular, you may have a font called "Arial Unicode MS". As far as I can
tell, this font has every character MS has ever needed. It's HUGE, weighing in
at 23mb: the biggest font I've ever encountered. I just checked, and my copy
of Arial Unicode MS (on the XP box, win7 didn't ship with it?!) does indeed
have those characters.
Another potential problem is that of ENCODING. I always suggest that folks use
"Identity-H". It gives you access to every character a font contains, across
all languages. It also has the side effect of forcibly embedding a subset of
the font in question. It's not always the way to go, but for 90% of the cases
out there, it'll work just fine... so long as the font has the characters
("glyphs" really, but that's another conversation) you want.

What is the correct Fond file that I have to use? I have used Arial and
Times New Roman. Neither would do the job correctly. It is in c# dot net
environment.
