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

[Markus Mützel]

Follow-up Comment #38, bug #57107 (project octave):

IIUC, your use case is exactly the type for which the proposed workaround
should be working. You could use something like the following:

first_non_ascii_idx = max([find(buffer>2^7, 1, 'first'), 1]);
regexp(buffer(1:first_non_ascii_idx-1), '^\s*(http|https|ftp|file)://');


That should be working in Octave and in Matlab. And maybe also speed up the
regexp if `buffer` can be very large...

Could you please clarify or show an example for which the above approach
doesn't work?
