including Angstrom and Greek letters in gnuplot?

Question

I am using gnuplot and would like to get the symbol for "Angstrom" (iso encoding 305) and the Greek letter Delta (Symbol 104) in the plot. How can I combine the two encoding schemes when producing my output eps?

Answer 1

This works without problem for me using UTF8 character for Angstrom and either the Symbol font or the UTF8 character for Δ :

set xlabel "{/Symbol D} Δ (Å)"

Gives in PDF terminal :

with encoding to default but UTF8 as system wide locale:

gnuplot> show encoding

nominal character encoding is default
however LC_CTYPE in current locale is fr_FR.UTF-8
