Comment(by hakre):

 I have problems with making assumptions based on own criteria. Even if
 only 1% of WordPress users are actually Authors of their CSS, well, ... .

 As this was requested in trac I took quite some time and analysis to find
 a good solution. The patch provides correctly encoded classnames based on
 WP Post Slugs. This really comes in handy. It provides IDs as well. This a
 solution that works very broad and is standard compliant.

 As for the generality of a clean_css_classnames() function, it must deal
 with all possibility according to the definitions. split_utf8() is a
 helper function sothat clean_css_classnames() can do its job.

 you can for shure in contrast reduce wordpress to ascii 7bit. but i
 assume, this is not intended by the wordpress core devs. so if the way
 leads to utf-8 and you need a function to clean css classnames, there it
 is. or should this run into the same dilemma as with clean_url()?.
