unicode characters in strings

[Alex-Jordan]

This line causes a string to be wrapped in \verb if it has any characters at all other than those prescribed here.

pg/lib/Value/String.pm

Line 109 in 5201eb8

return $self->verb($s) unless $s =~ m/^[-a-z0-9 ,.;:+=?()\[\]]*$/i;

I would like to use more unicode strings like say μ₁ here and there, notably in popup/dropdown answers where math content is not going to work. Since I use xelatex as the tex engine, in principle I can do this. But because of this wrapping in \verb, these end up in monospace font (once I've chosen a font that even has a monospace versions of, say, μ₁).

Can we rethink this line and make it more targeted for when it uses \verb? Would it work to only use \verb when the string has a special LaTeX character among [#$%&~_^{}\\]?

You would also need <, >, and |, at least, as these produce other characters when used in \text{}.
