Tools How to remove alphabets/special characters/space in the 5th field of a tab delimited file?

Thank you for 4 looking this post.

We have a tab delimited file where we are facing problem in a lot of funny character. I have tried using awk but failed that is not working.
In the 5th field ID which is supposed to be a integer only of that file, we are getting corrupted data as below.
I want to remove the entire corrupted data for the corresponding row & replace it with empty value.

i am not sure what are these symbles are and what command can replace these funny junk chars.

Your suggestion are appreciated.

Example:
Code:
record 1 - 
"14"    "50603" "1012"  "123"      "12ռ4�Z{>�}ŪiY2���3�'�ݐ؍>N�C�7>S"      "19-Mar-2014 14:58:26" 
record 2 - 
"14"    "50603" "1012"  "37164455"      "ռ4�Z>S"     "19-Mar-2014 14:58:26"

Output Should be like:

Code:
"14"    "50603" "1012"  "123"      ""     "19-Mar-2014 14:58:26"  
"14"    "50603" "1012"  "37164455"      ""      "19-Mar-2014 14:58:26"
