I found that the accented characters have wrong vertical spacing (and 
indeed the wrong shape as well) if you include accents and 
non-alphabetical characters the standard LaTeX way instead of the 
normal Unicode way, i.e.:

\"a instead of ä
\'e instead of é
`' instead of ‘’
``'' instead of “”
-- instead of –
--- instead of —
etc.

Maybe that's what affects you here. With XeTeX you really have to go 
Unicode all the way, I think.

Regarding the specification of \baselineskip, it's done in the arcane 
of LaTeX style files etc. and I wouldn't want to start fussing with 
this unless highly motivated to do so. For example, with the article 
style and 12pt option the \baselineskip for the normal size is defined 
in size12.clo:

\renewcommand\normalsize{%
    \@setfontsize\normalsize\@xiipt{14.5}%
    \abovedisplayskip 12\p@ \@plus3\p@ \@minus7\p@
    \abovedisplayshortskip \z@ \@plus3\p@
    \belowdisplayshortskip 6.5\p@ \@plus3.5\p@ \@minus3\p@
    \belowdisplayskip \abovedisplayskip
    \let\@listi\@listI}

where the second line says 12pt-size characters on 14.5pt leading, 
given that latex.ltx says:

  \def\@xiipt{12}

Hope this helps,
