[XeTeX] Coordinating fonts in text and math mode: question from a new user

[Peter Dyballa]

You're on a Mac. You can open the Character Palette utility and see  
which font has a particular glyph. You can also use a utility like  
UnicodeChecker for this. The Linotype Fontexplorer X or FontForge  
(needs X11) can show you which glyphs a font has.

When you look at the documentation for xltxtra ('texdoc xltxtra' on  
the command line) you can see some nice things, particularly the  
package's implementation, and here the definition for the \XeTeX  
logo. It uses the \rotatebox command from the graphics and graphicx  
packages. The fontspec documentation shows how to use (select from  
the font) lining or old style figures.

In XeTeX virtual fonts do not exist. Instead you can use Unicode,  
i.e., UTF-8 or UTF-16, i.e., ο or Ψ. But maths is a bit different  
than text.

Maybe http://xml.web.cern.ch/XML/lgc2/xetexmain.pdf gives some useful  
insights.

It isn't pollution that's harming the environment. It's the  
impurities in our air and water that are doing it.
