Hello Petr^2 & others, To Petr Olsak, who is not subscribed to the list: we're trying to prepare new unicode hyphenation patterns.
See http://www.tug.org/svn/texhyphen/ and http://tug.org/pipermail/tex-hyphen/ (I can copy-paste a longer explanation from older threads if needed.) I did not dare using the new loader for Czech and Slovak patterns since I suspect that I do not understand the macros to their full extent, and I have a feeling that these patterns might have used on might be used with some other encoding (il2?). And they might be used with some plain format. Currently XeTeX would load the new patterns, and pdfTeX & other 8-bit engines the old ones. It could have loaded the new one, but I'm not confident in all the possible border cases where the patterns might have been used. But if you (or some other expert from CS group) can have a detailed look and test if new patterns work even with pdfTeX, please let us know. It would be nice to move forward, but not for every price, and definitely not for the price of something-might-be-broken. Thanks a lot, Mojca
