问题
I'm trying to produce a plot where I have the character Å (angstroms) in the x axis. Moreover, I want this character to be in the same font as the rest of the graph, that is I want to use Times-Roman. If I use the following code:
set encoding iso_8859_1
set term postscript eps enhanced color "Times-Roman, 32"
set output "angstroms.eps"
set xlabel "Try1 {A} ({\305})"
plot sin(x)
I obtain this figure:
(note: the figure I get is in eps format, but I have to upload a jpg to stackoverflow)
If I remove the {A}, or change it into anything else like {B} I get this:
Finally, if I write:
set xlabel "Try1 (/E {\305})"
I get
where the Å symbol changed to sans serif font.
What's going on? Thanks for any help, Cheers!

Here two different scripts, which work for me with Debian x86_64:
set encoding utf8
set term postscript eps enhanced color "Times-Roman, 32"
set output "angstroms-utf8.eps"
set label at graph 0.1, graph 0.75 "Try1 {A} (Å)"
set label at graph 0.1, graph 0.5 "Try1 {B} (Å)"
set label at graph 0.1, graph 0.25 "Try1 (Å)"
set xlabel "Try1 (Å)"
plot sin(x)
I tested this one with 4.6.3 (needs at least 4.4 because of the utf8 encoding). As angstrom signs I used the LATIN CAPITAL LETTER A WITH RING ABOVE (U+00C5).
The other script is
set encoding iso_8859_1
set term postscript eps enhanced color "Times-Roman, 32"
set output "angstroms.eps"
set label at graph 0.1, graph 0.75 "Try1 {A} ({\305})"
set label at graph 0.1, graph 0.5 "Try1 {B} ({\305})"
set label at graph 0.1, graph 0.25 "Try1 ({\305})"
set xlabel "Try1 ({\305})"
plot sin(x)
That one I tested with 4.2.0 and 4.6.3. All variants give the same result:
I obtained that png using:
epstopdf angstroms-utf8.eps && pdftocairo -r 150 -png angstroms-utf8.pdf

In the mean time I found also this workaround, even if it is not so elegant:
set xlabel 'Distance ~A{1{^\260}}'
