Using " works most of the time, but, if you encouter some URL like 
http://bbs.ustc.edu.cn/cgi/sf?bid=260&aof=M425dea7e&fn=23.jpg
It does not work properly.

$ header http://bbs.ustc.edu.cn/cgi/sf?bid=260&aof=M425dea7e&fn=23.jpg

If I use wget directly with the single quotes around the URL, you can
see the differece easily:

$ wget -O /dev/null -S
'http://bbs.ustc.edu.cn/cgi/sf?bid=260&aof=M425dea7e&fn=23.jpg'
