I'm using the pre-release testing version of TeXlive 2010. From what I understand from the TeXlive Guide, a new feature is that support for magin kerning has been added to XeTeX.
From what I can tell, it is not enabled by default, though I'm not certain about that. (The effect might be subtle enough that I cannot tell.)
Is it possible for me to enable this when compiling a more or less standard XeLaTeX document? If so, how? The microtype package still throws an error when I try to use it with xelatex. Will there be an updated version of this package?
Will it be necessary to use certain fonts, or prepare/acquire a special configuration file for each font?
Anyway, I can find very little information about this new feature online. Any light that can be shed would be appreciated.
geometrypackage'sshowframeoption is to tell for certain how much margin kerning is going on. (Load it with thepassoption if you want to restrict it to just this task.) – Geoffrey Jones Sep 11 '10 at 08:39
