Each of the source files contain 3 versions of the same Latin text. The first is the plain Latin which hyphenates perfectly in all 3 files. The second is the same text but this time accented in the manner commonly used in liturgic books - the accent marks the emphasized syllable to facilitate public reading - this text does not hyphenate well in the first and third file. The third version is the same accented text but with discretionary hyphenation points (\-) entered at all legitimate places. This text also hyphenates perfectly in all three files. The first file (test3-a) is processed with pdflualatex, the second file (test3-b) is processed using pdflatex with the addition of a usepackage utf8 inputenc and the third (test3-c) processed with pdflualatex with usepackage utf8 luainputenc. I have to admit I am not sure I completely understand the potential role of luainputenc... It appears to me that the hyphenation process is failing in pdflualatex. Obviously having to enter all possible hyphenation points in advance makes it prohibitive. pdflatex produces the expected results. As it is my understanding that luatex is ment to replace or at the very least be equivalent to tex. I thought you would like to know of this experiment. No tags attached.

There is no prebuilt \'\ae in Unicode, so the result is the expansion of the word is "scienti\accent 1\ae que", and this is what is actually causing the problem. I'll dig further 2009-07-30 10:55 administrator   ~0000242 Should be fixed by 2932. This allows accent-generated kerns to end words, and that in turn will allow hyphenation if the "scienti" part of the word, just like in pdftex.
