[Octave-bug-tracker] [bug #57107] regexp functions fail on ISO-8859-1 input

[Qianqian Fang]

Follow-up Comment #27, bug #57107 (project octave):

I am wondering what is the status of this bug? 

unable to handle non-UTF8 input in regexp/regexprep can potentially break many
existing codes. This bug deserve to have a higher priority. MATLAB's
regexp/regexprep are able to handle those without any problem.

what's the downside of setting ISO-8859-1 as the fallback when encoding can
not be detected? throwing an error is quite an invasive solution to this
issue.

I encountered this bug when running tests on Octave 6.4 via github action (see
logs below). MATLAB and older versions of Octave do not have this issue
