@Fu It is an unusual thing to do; what I do is copy the Zero Width Space character (right-><-here) and paste it where I need it.
My computer has an app called Characters, where I can search for the name of a character to find and copy it. You can also probably google for "zero width space" and find a site with a copy button, too.
@golemwire LOL! So you don't know an ALT+ code or other short cut either, eh? Not to mention copy/paste on mobile is a pain. (BTW, soapbox here, please don't recommend corporate closed source propritary software inadvertnely by saying things like "Google" when a phrase like "internet search" would suffice.) ;-)
@golemwire interesting. How does one do that?
