escaping colon in bash script

Good day all, I am trying to write a script in which a command should contain the colon character ':'. Looking at this document, characters can be escaped using this character '^', but they do not mention the colon character.

The command should be: 

iwconfig wlan0 key s:AsciiPassword

So in my script I have something like:

iwconfig $interface key s:$password

When I run the first command manually, it obviously does what is expected, but the second one in the script, Nothing!!! Would appreciate any help

Update: I cannot really produce an output because the command does not produce any.

That document you link relates to windows.

In bash ; escape with '\'.

You also likely want to quote your variable expansions

I would imagine you need:

iwconfig "${interface}" key s:"${password}"

You may need to escape the :, though I doubt it. If so it would be:

iwconfig "${interface}" key s\:"${password}"
