The confusion was on my part - when I tried to look at the string after unescaping it I was getting a jumble of Unicode characters and not the ascii string I was used to.  I spent a lot of effort trying to get that back into the form that I saw in the past, not realizing I didn't have to.

But using your script and plugging that into wicd's wireless password works very well.

Essentially it boils down to:

Editing wicd's wireless-settings.conf:

identity = host/HOSTNAME.local.domain
beforescript = /usr/local/sbin/machine-passwd.sh

And then machine-passwd.sh is similar to:

wicd-cli -y -n (network-id)  --network-property password -s "${password}"

(I have a little logic in there to grab the network ID since it changes from time to time.)

Then when wicd connects, it presents the username of the machine account and the current machine password, whatever that may be.  I could probably work with your script to insert the password into wireless-settings.conf directly, but I’m too lazy to do that now that this is working.

Thank you very much!
