[Octave-bug-tracker] [bug #43651] special character (diameter sign) in plot produces warning or doesn't show up

[Rik]

Follow-up Comment #4, bug #43651 (project octave):

I checked the actual fontfiles using fontforge that I have installed on my
computer and, indeed, the version of Arial and Cambria I have do not have an
entry for 0x2298.

I set a breakpoint in the render code and checked the fontname just before it
attempts to map the Unicode number to a glyph index.  When it works, the font
name is '*' which is the default font.

To find the default font I used 


fc-match


on a shell command line.  I don't know if there is something similar for
Windows or not, but that's the only way I could figure out what the default
font was.

So far I think Octave is behaving correctly.  The glyph doesn't exist so it
issues a warning about it.  Even when using gnuplot, the glyph doesn't exist
but gnuplot seems to be substituting a character on its own.
