Remove special characters from string

Hi there,
I'd like to write a script that removes any set of character from any string. The first argument would be the string, the second argument would be the characters to remove. For example:

Code:

$ myscript "My name's Santiago. What's yours?" "atu"
My nme's Snigo. Wh's yors?

I wrote the following code:

Code:

$ cat myscript
ans=$1
for (( i=0; i<${#2}; i++ )); do
    ans=${ans//${2:$i:1}/}
done
echo "$ans"

But it doesn't work with the following special characters: #%*?\
Is there any simplier way to do that?
How can I make it work with all the characters?

Thanks in advance
Santiago
