[Octave-bug-tracker] [bug #39828] Missing symbols from new TeX interpreter

[Rik]

Update of bug #39828 (project octave):

                  Status:                   Fixed => In Progress            
             Open/Closed:                  Closed => Open

Follow-up Comment #42:

Re-opening this bug about the TeX interpreter to ask a question about two
symbols


\O : mapped to 0x2298 (Circled Division Slash)
\oslash : mapped to 0x2298


In Matlab, both of these symbols are mapped to 0x2205 (Empty Set).

In TeX


\O : mapped to 0xD8 (Scandinavian Captial O with slash)
\oslash : mapped to 0x2298 (Circled Division Slash)


Finally, TeX also has


\emptyset : mapped to 0x2205 (Empty Set)


It seems to me that Octave should map the capital '\O' to the Empty Set.  This
is compatible with Matlab and gives user's a way to actually get a circle
where the slash line extends outside the diameter of the circle, unlike
'\oslash' where the slash line is within the diameter of the circle.

As an addition, since Octave is a superset of Matlab, we could also offer the
expansion '\emptyset' which would also expand to the emptyset.

Is this a good solution?
