uppercase, small caps, numerals and German capital sharp s

[Thomas Fehige <thomas@fehige.de>]

Hello,

I'm new to ConTeXt and this list. After a long time of using LaTeX and 
xeLaTeX I was finally lured into trying ConTexT by its ability of grid 
typesetting.

Today's problem is a bit complex. In a book project I have several 
points where stuff is capitalized or turned into caps+smallcaps or pure 
smallcaps. My guess is that that should work either with \WORD{Stuff}, 
\Cap{Stuff} and \cap{Stuff} or with \uppercase, \sc, and 
{\sc\lowercase{Stuff}}. (Not quite, it seems)

I'll use a commercial font called Calluna, but have added Linux Biolinum 
O to the example for those who don't want to download Calluna (the 
"Regular" can be "bought" for free, e.g. at 
https://www.fontspring.com/fonts/exljbris/calluna).

Both Calluna and Biolinum contain the glyph "LATIN CAPITAL LETTER SHARP 
S" at "1E9E. I'm not sure if they contain a small or medium caps 
version. I'd like to use that glyph in the capitalizations mentioned, 
but it only works erratically (cf. example).

Also, Calluna comes with oldstyle numerals switched on, which is nice 
for normal text, but should change to lining numbers in all-caps and to 
small-cap lining numbers in all-small-cap text. I'm not sure what I'll 
want in a caps+smallcaps context, but certainly not oldstyle numbers 
with their descenders.

Any ideas? Thanks for reading! -- Thomas

PS: I asked the same question on stackexchange, there's also an image of 
the result of my example:
