Subject: Re: DOCBOOK-APPS: XEP for $80
The original TEX Portuguese hyphenation file is too primitive for serious use. It doesn't even allow diacritics, which is not only abundant in Portuguese, but affect hyphenation. (That seems also to be the case with Czech.) I wrote a better Portuguese hyphenation file to use in FOP (should be shipping with 0.25), but it would not work in XEP because in it the hyphenation points cannot be prioritized as they can in TEX and FOP (http://www.renderx.com/Tests/doc/fo/spec.pdf - section 5.4) In fact, since the whole idea of Liang's algorithm is based on this, I can't understand how such a simplified algorithm could perform well, unless it discards most of the valid hyphenation points. Have you tested XEP's hyphenation algorithm with a bunch of hard-to-hyphenate words? (For example, several words with tricky combinations of consonants and vowels around ? ). Nevertheless, "quite well" is a very subjective term. For some friends, TEX's old file (which doesn't hyphenate any words with diacritics but mostly works otherwise) is suitable. I had an extra job for being too purist in orthographic matters, but with XEP I couldn't even start, since we cannot correct or change its algorithm.

With the FOP classes <grin/> Not worth... Did you provided Portuguese hyphenation patterns to XEP? I did so for Czech and XEP hyphenation works quite well. I think that you can get PT hyphenation patterns from TeX distribution and use it directly with XEP (this way it worked for Czech).
