[Octave-bug-tracker] [bug #55195] "help" for core functions contains odd symbols for non-ASCII characters

[Markus Mützel]

Follow-up Comment #2, bug #55195 (project octave):

I had a look at the code for the lexer/parser again and  couldn't find
anything that would indicate whether a file is from core Octave, an (OF)
package or from a directory added by the user.

Maybe it would be handy if we would keep track of this. E.g., we cannot warn
at the moment if a user (unintentionally) overwrites a core function if it is
an .m file. Maybe "load_path" should distinguish if a file is "internal" or
"external". And that information could be fed down to the parser (via
"fcn_file_in_path"?).

Since this would be a bigger change and non-ASCII characters never really
worked correctly on previous version of Octave anyway (on non-UTF-8 systems),
this change should probably be postponed until after the Octave 5 release.
