Hidden chars in Unix can be replaced?

We have some unseen chars in unix, like '^T's, can be seen with 'cat -v' command.
Is there any way, with which, we can replace these ^T s with a space?

I have got the following solution.

cat -v file1 | sed 's/abc^T/abcx/g' > file2

Do anyone have better solution?
