Hello Pablo
I'm afraid I don't know LaTeX but I *think* that plain TeX commands will
still usually work. Anyway, once you've started a XeLaTeX document, you
might try the commands I gave (assuming you have Minion Pro on your system),
and it has since emerged from the contributions of others to this thread
that all you need to do to invoke polytonic Greek hyphenation rules is to
say:
\uselanguage{ancientgreek}
So the lines to paste in before a Greek passage (to see if they would work)
are:
\font \myfont = "MinionPro-Regular:+onum:mapping=tex-text:letterspace=12"
at 12pt
\tolerance 500
\myfont
\uselanguage{ancientgreek}
That should give you quite generously letterspaced Greek, with correct
hyphenation. (If these commands need to be modified for use in a LaTeX
environment, I'm sure someone else on this list will leap in. I *hope* it's
not the case that if you are using fontspec and/or polyglossia you are then
precluded from using the more primitive commands and macros that come
bundled with (Xe)Tex.)
Whenever you need letterspacing, you would just need to use \myfont within a
group:
Some text some text some text some text some text {\myfont some letterspaced
text} some text some text some text some text .

In plain XeTeX I find the passage in the URL works OK with letter-spaced
Greek if I give at the start:
\font \myfont =
"MinionPro-Regular:+onum:mapping=tex-text:letterspace=12" at 12pt

Hi John,
many thanks for your reply.
Sorry for not having answered before, but your reply was Greek to me (no
doubt, due to my own ignorance ;-)).
However, XeTeX doesn't know how to hyphenate Greek so to avoid overfull
rules I have to give \- explicitly at legitimate breakpoints where the
overfull rules occur. It's possible to invoke some of the old Babel
hyphenation patterns by using eplain (\input eplain) but unfortunately
Babel's Greek hyphenation patterns (in the hyphenation file
polutonigreek) are not tied to UTF Greek so have no effect. I don't know
if Babel is being actively maintained (since Polyglossia, which requires
LaTeX, is a much more sophisticated replacement), but if it were
possible to update its hyphenation patterns to cope with UTF input, that
would be a very welcome feature for plain (Xe)TeX users.
What I don't understand why polyglossia is problematic when hyphenating
ancient Greek with LetterSpace.
Pure XeTeX is totally foreign to me and I would need to use LetterSpace in
a number of documents.
Is there no way to solve this?
Thanks for your help,
Pablo
