Consider the consequences to a parser when there are multiple forms of what appear to be (say) "+" or "space" or "A" (is that a capital alpha?) .. Selecting Greek or other symbols from a palette might be cute. Freeform input of unicode, probably a bag of worms. RJF On Friday, February 21, 20

Who would do that ? You ? And which 73 others ? Unicode is Hge... Seriously : Such a proposal couldn't stop to "just" the "customary" single-letter greek variable names we are used to and think of first. There is no a priori valid reason to accept them and refuse, for example, hebrew or cy

A similar bag of tricks is available to users of sage-shell-mode in emacs, using TeX Input Method or one of its possible customizations. But such variable names may cause havoc in a \LaTeX output. Consider: sage: var("λ") λ This works sage: lat
