Helvetica Neue is not a free font and should be
put behind in CSS
font-family, like on Stackoverflow main site.
font-family: Arial,Liberation Sans,DejaVu Sans,sans-serif;
font-family: 'Helvetica Neue', Helvetica, Arial, Sans-seris;
There is a typo,
Sans-seris should be
Sans-serif, but that is not a problem.
Problem is that you have incomplete
Helvetica Neue font on your computer, or font doesn't support
“ character (and similar).
Arial is very similar to Helvetica, and majority of computers has it.
If non web safe fonts are used, they should be offered to be downloaded in CSS e.g
List of free webfonts: http://www.google.com/webfonts/
FYI, Helvetica Neue is not a WIndows system font. It is a system font
that is bundled with recent versions of the MacOS with some form of
the words Helvetica and Neue in the name of the font.
I see now that Wordpress is hiding beneath blog post. I have solution for that:
rm -rf wp-*. No wonder why Jeff is writing PHP rants when Wordpress is flagship of PHP with its maybe_ functions.
