Ah, yes that's probably what I should done to start out with. Now when I
switch html for xhtml, it somehow breaks my SVG-fixing script. I didn't know
that the html-option would produce partially invalid HTML, as it seems.

I used the options:

*\usepackage[html,fn-in,png,charset=utf-8]{tex4ht}*


But given that changing to xhtml things start breaking again, I think I will
leave all that alone.

What worked for me is another quick-fix, including the following two lines
in my script:

*rpl tspan span *html*
*tidy -utf8 -m -c --drop-proprietary-attributes true *.htm*l


Unless I have overseen something, it all seems to work out now. And the
epub-files that Calibre cna produce of it seem to work as well.

I guess everything is currently changing, like

bibtex -> biblatex
pdftex -> luatex
8 bit -> utf-8
PDF -> EPUB
PNG -> SVG
Kile -> LyX

Maybe that's why everything looks like it is in a semi-broken state right
now. I haven't been around long enough to know whether things always are
like this. I hope that over time I will be able to remove more and more
components of my monster-script, as the native applications manage to get
rid of their internal issues. I'll be happy to mail the script to anyone,
although it's really just a large and confusing piece of spaghetti-code to
anyone other than me.
