Ah yes, I looked into US International. However the fact that the accent deadkeys (', `, ~, ^, ") are common punctuation kinda messes up my coding productivity, so I had to find another way. macOS's Option + key chords are highly productive but aren't supported on all platforms, so I settled on the Compose key as a compromise. (my Compose key is mapped to the Menu key on Windows keyboards which almost nobody ever uses -- in contrast the Windows key is used a lot) Compose keystrokes are slower because they are sequences and not chords, but they're intuitive enough and work well for me.
