No, tex4ht/mkii (which use 8-bit-pdftex) can handle a much larger
part of utf8 the same way as tex4ht/latex can do it: by using
various font encodings.
tex4ht contains already a lot of support for various font encodings
so it is no wonder that a test with mkii gives something sensible.

No the euro is only a good test object as it is in ansinew encoding
but in unicode outside the < 256 block.
If you want to write a text with e.g. greek and english with
pdflatex you need at least two font encodings (T1 and LGR) and two
With luatex one encoding ("Unicode") and one large "unicode" font is
I want to find out if tex4ht can handle large "unicode" htf-fonts

dvi doesn't care about the input encoding, it encodes character
positions in fonts.
The dvi's generated by luatex (if I inspect them with dv2dt) look
actually quite similar to dvi's generated by latex. E.g. they
contain - if I use an unicode font and input an € - the entry "s1
8364" (8364 = hex 20AC). "Normal" dvi have similar entries - only
the numbers are smaller.
So tex4ht could work with luatex if
1. the tfm of the fonts loaded is not needed for something essentiel
(I hope only for ligatures) and that ine can use some simple
2. tex4ht can handle large versions of its htf-fonts and don't
tumble over the large character numbers.
I don't have time this week-end to make more tests but I will look
again next week.
