[Markus Mützel]

Update of bug #57107 (project octave):

                 Summary: regexp functions fail on ISO-8859 input => regexp
functions fail on ISO-8859-1 input

Follow-up Comment #20:

The attached patch wires in the validation of UTF-8 at a pretty low level. It
applies on top of "bug57107_validate_u8.patch".
It breaks "strread" and "textread" (and possibly also other things). But I'm
still waiting for feedback on the maintainers mailing list to see if it is
worth looking into why.
Nevertheless, it demonstrates what could happen:

octave:1> char (181)
ans = µ
octave:2> double (ans)
ans =

   194   181

octave:3> char ([181 228])
ans = µä
octave:4> double (ans)
ans =

   194   181   195   164
