Hello LyXers,
I've seen that lyx internal format suports accents with this codes:
\i \'{letter}<CR>
where letter is a | e | i | o | u and <CR> is a carriage return
It also supports
\i \~{n}<CR> for an n~ (ntilde)
But, for default, the internal format uses the accented characters directly and not the codes above, and this causes me troubles with Latex2Html.
What I like to do is that my lyx uses this codes by default ...
Maybe I have something wrong, and this a mistake in my machine configuration which is:
Redhat 8.0 Lyx 1.3.2
Try using lyxport (http://www-hep.colorado.edu/~fperez/lyxport/) I don't remember what I did, but it seems to fix whatever the encoding issue is. I just wrote a simple test with accents (same platform as you), and while Lyx's 'Export to HTML' does indeed fail, lyxport succeeds.
Best,
f.
