[XeTeX] VIQR pre-processor wrotten in (Xe)TeX ?

Hi there,

It might be slightly off topic, but wouldn't it be simpler to enter
unicode directly into your tex file?  After all, we're using xetex.

I can see the usefulness of creating a mapping for the long term, as a
general tool.  It would be of great help if one uses a text editor
that doesn't support unicode.  For that matter, doing something
similar for TELEX or VNI should be an added goal.

But back to Philip's original problem (of typesetting a restaurant
menu), I would do that by entering unicode directly.  For example on
my mac, I would choose VIQR as an input method and type the
multilingual text directly in texworks, texshop, or emacs (aquamacs),
and declare an appropriate font in my tex file.

Sorry for not providing insights about the mapping issue.  Best,
Nguyễn Quang Minh || 阮光明
