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.

  • Margin kerning can be seen easily. All punctuation (hyphens, commas, ...) at the end of a line are placed a little further to the right, so the right margin of the body of text is formed by the letters, but not by the punctuation. Commented Sep 11, 2010 at 7:36

    One of my favourite uses for the geometry package's showframe option is to tell for certain how much margin kerning is going on. (Load it with the pass option if you want to restrict it to just this task.) Commented Sep 11, 2010 at 8:39
  • Thanks for the suggestion, Geoffrey. This makes it easy to see that there's definitely no margin kerning going on by default.

You need to install a preliminary version of the microtype package.
