I want to remove all the non-ASCII characters from a file in place.
I found one solution with tr, but I guess I need to write back that file after modification.
I need to do it in place with relatively good performance.
Any suggestions?

# -i (inplace)
LANG=C sed -i -E "s|[\d128-\d255]||g" /path/to/file(s)
The LANG=C part's role is to avoid a Invalid collation character error.
Based on Ivan's answer and Patrick's comment.
