It was just brought to my attention that copy/pasting the :iconplz: codes from the deviation descriptions, such as the ones found HERE, no longer works.
I've done a bit of testing and it seems to be a problem that only happens if you're using Chrome.
To make the :iconplz: codes show without becoming icons, we have to inject some HTML codes.
It seems that chrome copies the HTML code/formatting within the text instead of just the text as most other browsers do.
Luckily it's easy to work around!
1. Select the code and copy it (Ctrl C)
2. Rightclick where you wish to paste the code.
3. Select "Paste as Plain Text"
Hope this helps anyone out there who was struggling with this problem!
