Best way to input Vietnamese unicode characters?

I looked here:
http://homepage.mac.com/herr/

I could not get any of the Mac stuff there to work but
it did lead me here:

http://prdownloads.sourceforge.net/unikey/uvconv-1.1.3b.tar.gz

I compiled the above software and wrappped the executable in a simple shell script.

The script accepts a .txt file with VIQR in it and outputs the result in
a file with dual suffix:
.html.utf8

I use camino or safari to display it.

Then I can grab it with my mouse and paste it where needed.

It would be nice if I could find something that would
allow me create utf-8 Vietnamese characters directly
from my keyboard, but I'm getting good at writing VIQR
into .txt files.

Here is an example of VIQR:
Tie^'ng Vie^.t

And the resulting utf-8:
Tiếng Việt
