;;; Commentary:

;; Tai Viet is being included in the Unicode at the range U+AA80..U+AADF.

TaiViet refers to the Tai language used by Tai people in
Vietnam, and also refers to the script used for this language.
Both the script and language have the same origin as that of Thai
language/script used in Thailand, but now they differ from each
other in a significant way (especially the scripts are).

The language name is spelled as \"ꪁꪫꪱꪣ ꪼꪕ\", and the script name is
spelled as \"ꪎ ꪼꪕ\" in the modern form, \"ꪎꪳ ꪼꪕ\" in the traditional
form.

As the proposal for TaiViet script to the Unicode is still on
the progress, we use the Private Use Area for TaiViet
characters (U+F000..U+F07E).  A TaiViet font encoded accordingly
is available at this web page:
