I don't really understand how tex4ht selects unicode.4hf files. On my
machine, it always selects the one in charset subdir, I don't even know
how it is possible to select one in another subdir. Surely with
tex4ht.env edit. So it is definitely strange that in Miktex it selects
unicode.4hf in charset/uni dir. Does it work in this way also in Windows
TL? Maybe there is an old version of tex4ht.exe?
