One of the functions of DFLT, as I understand it, is to provide access <br>
to OTL processing for PUA encoded characters. Since PUA is used to <br>
encode conscript and conlang characters that are excluded from standard <br>
Unicode encoding, but which function in parallel to conventional scripts <br>
and languages, it makes sense to me that DFLT should be able to take <br>
language system tags.<br>
<br>
For example, Tolkien's Tengwar script was conceived by him for the <br>
writing of two different Elvish languages — Quenya and Sindarin —, and <br>
enthusiasts have adapted it to write a number of other languages <br>
(including earthly human languages). It seems to me quite conceivable <br>
that Tengwar font makers may wish to vary behaviour of the script on a <br>
language-specific basis. And of course, since Tengwar is a complex <br>
script but excluded from Unicode, they are dependent on PUA encoding and <br>
DFLT script OTL processing.<br>

Getting Spiekermann to not like Helvetica is like training<br>
a cat to stay out of water. But I'm impressed that people<br>
know who to ask when they want to ask someone to not like<br>
Helvetica. That's progress. -- David Berlow<br>
