Well the general principle easy.

In the env-file there are blocks e.g.

<symhtf>
i/tex4ht/ht-fonts/symbol/!
i/tex4ht/ht-fonts/unicode/!
i/tex4ht/ht-fonts/ascii/!
i/tex4ht/ht-fonts/alias/!
</symhtf>

and with the -c option you are chosing such a block. -cunihtf will use
the <unihtf> block, and -csymhtf the <unihtf> block.
The <default> block seem to be the fallback.

The problem are the finer details, miktex seems to need two subfolder
levels, while texlive seems to look only in the next subfolder.
