Follow-up Comment #1, bug #55195 (project octave):

No answers, just a couple observations after looking at this for a minute.

Octave assumes that all texinfo text that goes into the user manual (including
all core function doc strings) is UTF-8 (see the @documentencoding declaration
in doc/interpreter/octave.texi).

Only one core function doc string contains its own @documentencoding
declaration, the 'slash' function. The content of the 'slash' function doc
string is entirely ASCII encoded. The rest of the core functions are
implicitly UTF-8 because the complete user manual is declared to be UTF-8.

Only two core function doc strings use any non-ASCII characters in their raw
markup. The 'strftime' function uses a single '±' character, and the
'unicode_idx' function (new in Octave 5) uses a 'ä' character. These are both
built-in functions, so I'm not sure whether mfile_encoding has anything to do
with their doc strings. Does it?

I think that we should be able to assume that all core doc strings are UTF-8,
whether or not they contain a @documentencoding declaration.
