Follow-up Comment #17, bug #43651 (project octave):
Ideally we should use the Symbol font so that printout and onscreen glyphs
match. On my system, "fc-match -v Symbol" tels me the font files is a sym link
to "/usr/share/fonts/type1/mathml/Symbol.pfb".
I used fontforge to inspect this file and I was not surprised to see that the
glyphs we think are missing are actually present: that is why ghostscript is
able to find them and put them in a png.
The problem is the mapping from a character to a glyph, and that is where I
get lost. Let me take an example: "\alpha" is glyph #97 ("a") in a 1 byte
Symbol character set (like the one used in postscript) and #945 in unicode.
There are additional information in font files to indicate which gliph
correspond to what unicode or 1 byte character, but I still have to play with
fontforge to understand this. At least what I already can say is that the
unicode code for "Copyright" is not filled (it is -1 ataully) in my
Symbol.pfb.
