removing multibyte characters from a file using sed

Question

i need to remove all multibyte characters from a file, i dont know what they are so i need to cover the whole range.

I can find them using grep like so: grep -P "[\x80-\xFF]" 'myfile'

Trying to do a simular thing with sed, but delete them instead.

Cheers

LANG=C sed 's/[\x80-\xFF]//g' filename
