Sorry, I could have explained you a bit better. See below.

The files are stored under
    http://www.tug.org/svn/texhyphen/trunk/hyph-utf8/tex/generic/hyph-utf8/
(you may browse through the repository).

But the files of particular interest to you are the following:

patterns themselves, in UTF-8 encoding:
http://www.tug.org/svn/texhyphen/trunk/hyph-utf8/tex/generic/hyph-utf8/patterns/hyph-cs.tex
http://www.tug.org/svn/texhyphen/trunk/hyph-utf8/tex/generic/hyph-utf8/patterns/hyph-sk.tex

pattern loaders:
http://www.tug.org/svn/texhyphen/trunk/hyph-utf8/tex/generic/hyph-utf8/loadhyph/loadhyph-cs.tex
http://www.tug.org/svn/texhyphen/trunk/hyph-utf8/tex/generic/hyph-utf8/loadhyph/loadhyph-sk.tex

conversion from UTF-8 into EC/T1/Cork encoding:
http://www.tug.org/svn/texhyphen/trunk/hyph-utf8/tex/generic/hyph-utf8/conversions/conv-utf8-ec.tex

The new patterns are not really encoding-independent, but the
conversion into EC encoding should work OK (I hope). One should load
loadhyph-cs.tex which loads the converter first, and then the patterns
themselves.

I believe that conversion should be OK for both Xe(La)TeX and
pdfLaTeX, but I have no idea about csLaTeX and csplain. That's what I
would like to ask you about.

Do these patterns work OK in csplain and csLaTeX? (Even if they don't,
you may still load your own patterns in csplain, but it would be
really nice to unify as much effort as possible.)
The question is - if we put these new patterns into language.dat -
would everything else still work OK?

In theory it should work, but I have absolutely no idea about details
of how csplain/csLaTeX works. Hans even supported some il2 encoding in
ConTeXt (which was not compatible with ISO Latin 2), and I know that
you had some special fonts.

So if any CS user would be willing to check ... I would be most
grateful for that.

Thanks a lot,
