I think the issue that I can't figure out is that even though I've edited the 
styles.css properly, plaintxtblog still inject the following from the theme 
options: 

<style type="text/css" media="screen,projection"> 
/*<![CDATA[*/
/* CSS inserted by plaintxtBlog theme options */
body{font-family:verdana, geneva, sans-serif;font-size:70%;}
body div#content div.hentry{text-align:left;}
body div#content h2,div#content h3,div#content h4,div#content h5,div#content 
h6{font-family:verdana, geneva, sans-serif;}
body div.sidebar{text-align:right;}
body div#container{float:right;margin:0 0 0 -320px;}
body div#content{margin:0 0 0 320px;}
body div#primary{float:left;}
body div#secondary{float:right;margin-right:20px;}
body div.sidebar{border-right:5px solid #ddd;padding-right:15px;}
/*]]>*/
</style> 

So how can I hack the theme options to include the fonts I'd like to add to the 
site. I need to add some special fonts since the site will be using multiple 
languages, some of which are non-latin scripts.
