Reminds me very much of UnicodeMath (https://www.unicode.org/notes/tn28/UTN28-PlainTextMath-v3.1....), in a similar way like J works around APL symbol with Ascii characters.
sum from {i=1} to n {i sup 3} = ({n(n+1)} over {2}) sup 2Someone’s gotta try to push the status quo forward on Unicode input.
For instance, while writing, the user inputs \alpha and the editor automatically converts it into the greek symbol right there in the source file. Later, when compiling latex transparently recognizes the greek symbol for what it is.
Sometimes I fire up a Julia repl purely as a unicode-getter.
