Apologies for the double email. 

I raised just after sending the previous one that using the ‘proper’ utf-8 hyphen character (0x2010) instead of 0x002d solves the issue. 
I'd be interested to hear if someone has an easier-to-type solution, though.

Hello,

Is there a way to preserve hyphenated words in the html export?
When exporting a document with ConTeXt, hyphens in the middle of words seem to be replaced by soft hyphens, which are not displayed by my web browser.

Minimal example: 

\setupbackend[export=yes]
\starttext
co-worker
\stoptext

The resulting .html file contains:
<div>
co­worker</div>

(There is apparently a soft hyphen between ‘co’ and ‘worker’. The pdf seems to render correctly.)

Cheers,
Florent
