Hi there,
I have just accidentally discovered that LetterSpace behaves differently
if the whole paragraph is set with this feature or not.
The minimal example:
\documentclass[12pt]{article}
\usepackage{fontspec}
\setmainfont{Theano Didot}
\begin{document}
χαλεπὰ \addfontfeature{LetterSpace=12}τὰ καλά
χαλεπὰ τὰ καλά
χαλεπὰ \addfontfeature{LetterSpace=0}τὰ καλά
Beauty \addfontfeature{LetterSpace=12}is difficult
Beauty is difficult
Beauty \addfontfeature{LetterSpace=0}is difficult
\end{document}
If you copy the resulting text (from
http://www.ousia.tk/wrong-letterspace.pdf), you will see that only the
second line is properly typeset, or at least, there are no blank spaces
between letters.
I guess this might be a probable cause for wrong hyphenation when using
LetterSpace. (BTW, loading polyglossia makes no difference.)
Have I hit a bug in LetterSpace? Do you know any way to avoid this?
Thanks for your help,
Pablo
