Now, after looking at this in a browser where the
\text?oldstyle characters failed, I am remembering that the
codepoints from U+E000 to U+F8FF are a private use area,
and, therefore, the values above for \textoneoldstyle and
\textnineoldstyle can only work with special arrangements.
I don't know what the values for these should be. Tex4ht's
invocation of the private use area suggests to me that the
\text?oldstyle characters do not have public codepoints.
I decided to run your example through xelatex (using
textcomp and not fontspec). It used the unicode font
LMRoman. I examined that and found \textoneoldstyle in the
private use area at F644 and \textnineoldstyle at F64C. I
then modified tex4ht's codes to use those values and
modified tex4ht's html output to invoke my webfont version of
Latin Modern Roman (made from lmroman12-regular.otf as found
in texlive using Jonathan Kew's sfnt2woff and served through
my private web server). It works.
