[Octave-bug-tracker] [bug #57107] regexp functions fail on ISO-8859 input

[Markus Mützel]

Follow-up Comment #10, bug #57107 (project octave):

After a little research, I don't think that we should sniff the encoding.
Instead we might want to select one of the fallback options for decoding
invalid UTF-8 byte sequences [1].

I'd personally vote for the option:
"The Unicode code points U+0080–U+00FF with the same value as the byte, thus
interpreting the bytes according to ISO-8859-1."

That also most closely matches what Matlab seems to be doing. And it would
also solve the OR.
