The particular issue is the correct
representation of Sidak's name, which
in TeX would be
\v{S}id\'ak
i.e. hacek(*) or circumflex accent sitting on the S and
an acute accent on the a.
Using the same configuration as Roger, except Windows
XP, and Stata's own fonts, I find that
. di "Sid{c a'}k"
shows the accent correctly in the Results window, but
the corresponding element in a .hlp does not
show correctly in the Help window (Viewer).
The hacek(*) I don't know how to do.
(*) This word should itself be accented.
