This simple text editor supports the entry of Unicode symbols with LaTeX commands. LaTeX commands are parsed and automatically converted into their Unicode equivalents according to unimathsymbols.txt. It also saves your text to local storage so that it persists between sessions, e.g., you accidentally close your tab. The implementation is somewhat janky and highly unoptimized—every edit is 𝒪(n)!—so don’t write a book in this or anything.
