Maths symbols

What is the best way to get maths symbols in gnuplot? I currently
want the square root symbol. \sqrt{..} doesn't work.

There cannot be a single "best" way like that. The variety of output
formats is a good deal to big for that.

\sqrt could work just fine if your output is TeX-based. Other formats
may fare better with literal sqrt characters in the command, e.g. using
UTF-8 input and text storage methods.

from gnuplot 5.4 up you can use the direct unicode input.

set label '\U+221A'

After some fiddling I arrived at this:

set xlabel '{/Symbol=32 1/\326 T}'

It sort of works but can I get the T closer in under the sqrt?
I.e. is there a negative spacer, like \! in laTeX?

put the T in {}

set xlabel '{/Symbol=32 1/\326{T}}'
