Yes I know. I'm not wondering about this.

But why do I have two in the iso8859/1/charset folder?

Only "iso8859/1" has a "uni" subfolder in the charset folder with an
additional unicode.4ht.

E.g. compare in your list iso88859/1 with iso8859/2:

2 versions here:

> tex4ht.dir/texmf/tex4ht/ht-fonts/iso8859/2/charset/unicode.4hf
> tex4ht.dir/texmf/tex4ht/ht-fonts/iso8859/2/html/charset/unicode.4hf

but 3 versions here:

> tex4ht.dir/texmf/tex4ht/ht-fonts/iso8859/1/charset/uni/unicode.4hf
                                                     ^^^ odd
> tex4ht.dir/texmf/tex4ht/ht-fonts/iso8859/1/charset/unicode.4hf
> tex4ht.dir/texmf/tex4ht/ht-fonts/iso8859/1/html/charset/unicode.4hf

That's a bug in miktex.

somehow the ! in e.g.

    i~/tex4ht.dir/texmf/tex4ht/ht-fonts/unicode/!

is not correctly interpreted and doesn't work if the subfolder is
exactly one level down, so files in

texmf/tex4ht/ht-fonts/unicode/charset are not found, while
texmf/tex4ht/ht-fonts/unicode/charset/uni works.
