Replacing hex characters
I have the following file consisting of dates and sample measurements:
Code:
05��Oct��2010	1.31��
06��Oct��2010	1.32��
07��Oct��2010	1.31��

The hex characters are \xc2\xa0 in sequence.
I have tried to remove the characters as follows:
Code:
sed -i '' -e 's/\xc2\xa0//g' file.dat

and as follows (replace characters with a space):
Code:
tr '\194' '\032' < file.dat > file_.dat
tr '\160' '\032' < file_.dat > file__.dat

However, neither method worked. The first probably couldn't find the characters and left the file untouched and the second replaced some of the hex characters with other hex characters.

Can someone point out the mistakes or indicate an alternative method?
