wxMaxima allows to use engineer-style subscripts in variable or function names:

R_100=U_In/I_Out;
/* [wxMaxima: input end ] */

If this feature is over-eager (or not eagerly enough) wxMaxima offers additional control:

Equipping any character with accents

/* [wxMaxima: comment start ]
Unicode supports so-called "combining diacritics" that allow to assemble a character from several elements. Maxima might not know that the individual parts these characters are combined to are meant to be interpreted as ordinary letters, though, so assembling weird characters is a multi-step process:
[wxMaxima: comment end ] */
/* [wxMaxima: subsect start ]
Easy access to combining diacritics
[wxMaxima: subsect end ] */
/* [wxMaxima: comment start ]
* Open the "mathematical symbols" sidebar (if it isn't already displayed) and right-click on it
* Drag-and-drop a combining diacritic to the "add new symbols" dialogue, for example one of the following.
* The "symbols" sidebar now should allow for easy access to these characters.
[wxMaxima: comment end ] */
/* [wxMaxima: comment start ]
A few combining diacritics are:
[wxMaxima: comment end ] */
/* [wxMaxima: comment start ]
* ̂
* ̃
* ̅
[wxMaxima: comment end ] */
/* [wxMaxima: subsect start ]
Actually using combining diacritics
[wxMaxima: subsect end ] */
/* [wxMaxima: comment start ]
* First enter the character you want to equip with new accents or the like.
* Then add a Backslash ("\") in order to tell maxima that the symbol that now follows is to be interpreted as an ordinary character
* Then add the combining diacritic(s):
[wxMaxima: comment end ] */

Pre- and post- super- and subscripts

/* [wxMaxima: comment start ]
Thanks to Robert Dodier it is now possible to equip variables with super-, and subscripts that are displayed left of the variable name, too:
