Compose o dash. Windows doesn't have an easy way to map in the compose key (usually ralt)?
big if true, jesus christ microsoft
Note: bitwize is talking about how to do it on Linux. Which is the best way in my biased opinion. Perhaps not the best mapping for people who use it regularly but is awesome for those who use it irregularly. We can usually guess how to do weird diacritics without having to look it up.
Nope. When on Windows I tend to use one of the US International or the Pseudo VT320 layout from https://keyboards.jargon-file.org/ .
https://github.com/ell1010/wincompose is like the first thing I install on any new Windows machine.
