A happy new year to everyone!
I’m trying to generate PDF/A compliant files and have a Problem with chemical
formulas in text.
The following does not work:
\setupinteraction
[title=TITLE,
subtitle=SUBTITLE,
author=AUTHOR,
keyword={{KEYWORD1, KEYWORD2}, KEYWORD3}]
%% For PDF/A
\setupbackend[
format={pdf/a-1b:2005}, % or pdf/a-1a:2005
profile={default_cmyk.icc,default_rgb.icc,default_gray.icc},
intent=ISO coated v2 300\letterpercent\space (ECI)]
%% Tagged PDF
%% method=auto ==> default tags by Adobe
\setupbackend[export=yes]
\setupstructure[state=start,method=auto]
\starttext
\chapter[chap:testing]{Testing}
Das kann man auch als Textformel darstellen: \chemical{2 H_2,PLUS,O_2,GIVES,2
H_2O}.
\input tufte
\stoptext
If I include the \chemical command inside a
\startchemicalformula \stopchemicalformula
everything works.
What am I missing?
Greetings Axel
