Dear Reinhard / Thanh -- Many thanks for your comments. I'm sorry that "adding new features to pdftex is not desired now", but I guess if it's good enough for Don, then it's good enough for Thanh :-)
As for the original problem, I expect Thanh would use a Vietnamese font to typeset Vietnamese names.
Reinhard's closing observation :
And changing the matrix isn't sufficient. You'll certainly have to adapt the .tfm files.
I can't see why this is the case : once PdfTeX has read the TFM file, is it not sufficient "simply" to manipulate its internal version thereof,
The "" marks are the key. ;-) Side note: in luatex you can already do things like this by creating a virtual font or even a single virtual character on the fly, using a lua table to define the virtual commands. Best wishes, Taco
