charset utf-8 declaration in CSS causes Safari to not display background

Have noticed before that if I create a new CSS file in DW it automatically puts these two lines at the top of the file:
@charset "utf-8";
/* CSS Document */

I always ignored that until yesterday when, in answering a question here on EE someone pointed out that my solution wasn't displaying correctly in Safari. Upon digging a bit, I found that the "@charset "utf-8"" statement was the culprit -- Safari would not display the background color on my <body> tag unless I deleted that charset line. Sample code below can be used to see the problem in action.

So my questions are:
1. is this a Safari bug?
2. is there some preference in DW that I should change so it doesn't automatically add that line, or uses a different format?
3. will there ever be a case where deleting that line from my CSS will cause some other problem, or can I just delete it from all my CSS files with impunity?

Will split points to anyone with relevant input.

/* CSS Document */
body {background:blue;}
