Typing should not be a problem generally. There are a lot of 3d-party apps which
can bind a key to specific char input, system-wide. On windows I use Autohotkey.
But no 100% guarantee of course for any editor.

The chances to see that "delta equal to" sign in some random font /
random app is not so big.
It's only if you have fonts fallback system setup, and by default on
my windows it seems to
work only in Firefox browser.
