Show hidden characters

When I copy from some online sources, SUBLIME editor will show some hidden characters like
<#12332>

but these are visible in Drafts.
On some occasions, this has messed up copy and pasting a password.

Can we get an option to show this hidden code?

I just want to give another warning about this to everyone, because this cost me a while to figure out.

IMHO, it’s a bug.
