[XeTeX] Problem changing default fonts

[Michiel Kamermans]

Drébon,

in the world of typography it is a well known fact that Helvetica and 
clones lack small-caps, and many vehemently argue that this is right and 
proper, because "it is in a typeface family that shouldn't have 
small-caps". However, that means the trick is actually really simple: 
don't try to find a Helvetica clone with smallcaps, but simply find a 
different font that has a small-caps set that fits the visual style your 
publication uses, and then use that font instead of your main font when 
you need to run text in small-caps.

When one font doesn't offer what you need, use more fonts! (for 
instance, the combination of Palatino Linotype main text with FreeSerif 
punctuation looks far better than pure Palatino Linotype. Heresy! But it 
does anyway =)
