[NTG-context] utf 8 / test file

[Hans Hagen]

Hi,

I posted

   http://www.pragma-ade.com/temp/titus.pdf

now, one thing with unicode (utf) is that support needs to have an 
associated font / language switch.

Traditionally, tex font mechanisms have been complicated by the fact that 
there are many shapes per font and math has to be dealt with.

If we're dealing with say sanskrit, is it then safe to assume that

(1) we can switch to the language (if not yet done) when we encounter a 
unicode from the associated char/glyph range

(2) can we assume that a relatively simple font mechanism is used 
(normal,bold,slanted)

(3) can we assume that only a few (possibly derived from unicode) fonts are 
used, or at least one main type of font per language

(4) can we standardize on utf-8 [and assume some preprocessor if not]

[let's try to deal with the practical, so what's the practical usage]
