No, deleting the font cache will not correct the font issue on 
10.6.7. But it is also true this problem will not impact all 
users of 10.6.7. For the problem to be apparent you must be 
using an Opentype PostScript font and you must be using an 
application such as Adobe Reader that relies on Mac OS X to 
render the font. The work arounds are, don't upgrade to 10.6.7, 
don't use Opentype PostScript fonts or use another app to view 
the PDF file that either has a built-in rendering engine or 
Preview which ignores the problem.

See <http://db.tidbits.com/article/12078> for a more complete 
description of the issue.

But also note, it remains possible to corrupt font caches with 
10.6.7 regardless of the font type. And if you do have a 
corrupted font cache, then deleting the font cache will cause 
the cache to be re-built correcting the corruption.
