Nice. An alternative is to use a Compose key. I have Caps Lock mapped to Compose, and for example Compose-g-D yields “Δ” (“greek D”) and Compose-<-= yields “≤”, etc.

On Win10 the quick and dirty solution is to select a character on its own, copy it to the clipboard, then, in your clipboard history, pin that particular selection. Nearly every time you use it you'll have to scroll to the bottom of your clipboard history and then probably back up again a bit, but that's not all that bad.

Of course you HAVE already turned on your Windows 10 clipboard history, RIGHT? ;) https://www.howtogeek.com/671222/how-to-enable-and-use-clipb...

There is an implementation of xcompose for windows. I think it's called 'wincompose' or something like that.
