Bold font in subscript

[Nakita]

Dear all,
I want to make gnuplot to use "Bold" fonts by default, so I set the "termoption":
set termoption font "Times New Roman:bold, 24"
However, I recently noticed that this only applies to normal texts and subscipts with only one character, eg, "S_i". If I put more than one characters in subscrpts in curly braces, such as "A_{ij}", gnuplot will not render the "ij" in bold faces.
The minimal test codes:

set termoption font "Times New Roman:bold, 24"
set xlabel "S_i"
set ylabel "A_{ij}"
p sin(x)

One can notice that the xlabel can render the subscript "i" in bold faces while the "ij" are not rendered in bold faces.
So is this a gnuplot bug or I am missing something here?

Sorry, I don't have answer, other than it probably varies by term and you could try a different output? Just a suggestion though, and I don't know if it'll work. I remember years ago having to use the postscript term and then editing the file in a text editor to get things like this to work!

Appears to be a bug.
Examining the .eps file in a text editor shows that ij is not in bold

Find "(ij)" in the file and edit the preceding

s/(Times-New-Roman)/(Times-New_Roman:bold)/

It is the only occurrence of "Roman)" in the file.

FWIW The first EPS rendering engine I tried to view it with didn't
honour "Bold" at all (it has problems with Greek letters too) :(
