Theme editor converts \00BB \0020 into 0BB �020 broking the css

[nukeador]

Using the WP in-build theme editor, I've just realized that if I add to the style.css:

content: "\00BB \0020"

Once you updated the file, WP converts it to 0BB �020, which most browsers are unable to handle, causing css not to load property (gecko browsers are the only one that handle this with no error).

This is a big problem since the default theme use
content: "\00BB \0020" in its css.

Worksforme.. May need some extra information on the character set in use by the browser and the server..
