@vars and "pretty names"

[ko56]

Can someone explain what are the limitations of names in @vars? For example, I want to use a definition of this form:

@vars ys => "$y^*$"

where I've written LaTeX code for the name. Is this kind of thing possible? How do I do it? And what about things like $y^*_1$?

You can use unicode values, but I don't know that arbitrary LaTeX will be okay. The available Julia unicode subscripts and superscripts are:

julia> \_
\_(     \_-      \_2      \_5      \_8      \_a      \_e      \_i      \_l      \_o      \_r      \_schwa  \_v
\_)     \_0      \_3      \_6      \_9      \_beta   \_gamma  \_j      \_m      \_p      \_rho    \_t      \_x
