[XeTeX] Dotless I and Emph problem

[David Perry]

Hi Chris,

Those who know more than I can perhaps explain why this is happening 
(since the traditional TeX keystrokes for accented letters and things 
are supposed to be replaced by their Unicode equivalents when you use 
xlxtra--maybe something about the \emph command).

The quick fix, of course, is to use the actual Unicode i-acute, i.e., 
Fíthal; this works fine for me with Linux Libertine (the TT version; I 
don't have Libertine O installed, but that should not matter).  I 
realize that the traditional shortcuts are convenient for typing; if you 
need a lot of accents and want to enter them directly, try the 
US-International keyboard on Windows or the option keystrokes (option-e 
for acute, e.g.) on Mac OS.  That way you see the actual characters, 
which is kind of nice too.
