[tex4ht] Bold index entries

[Michal Hoftich]

Hi Jürgen,

> Now, as far as I can tell, if I just press <return> on each instance the ebook still has a hyperlinked index with bold entries at the right places - but it is annoying to have to do this each and every time I compile. Does anyone know a way around this?

Do you still use the workflow described here:

correct result using the code from my answer.

Best regards,
Michal
