I was wondering if there was an awk/sed regex that I can use to detect any lines that contain non-english characters, for example:

あと１つのスマッシュが見つからへん…もう寝よう
ความหวังดีของคนเรา สุดท้าย
Το θερμόμετρο χτυπάει
LA #MACIF a félicité #DotYou pour le site http://www.roulonspourlavenir.com , un petit compliment dans un monde de brutos... c'est bon ça!!

but since they are twitter posts, I need to keep lines with links, @ symbols, therefore I believe I am looking to detect any non-ascii characters?

Thanks for any help,

Tomek
