How to obtain tilde or approx symbol in gnuplot legend?

Question

I want to use either tilde (~) or approximate symbol (in latex \approx) in the legend of my gnuplot.

I am using epscairo terminal.

I tried seting either: set encoding iso_8859_1

or

set encoding utf8

and using different commands, for example \176 as descbribed here (http://ayapin-film.sakura.ne.jp/Gnuplot/Docs/ps_guide.pdf), but nothing seems to work.

Thanks in advance! :)

If you use utf8 encoding, you can copy any symbol into your script (if the font you use supports it, of course). — Karl, Jun 10 '15 at 20:05

It seems '\~' or "\\~" works for me for tilde. "{/Symbol \273}" produces ≈.

Thank you! I did not use both /Symbol and \273 at the same time! – nevermind Jun 10 '15 at 13:02
