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

[Markus Mützel]

Follow-up Comment #16, bug #57107 (project octave):

I just checked in a patch for bug #55452. With it, I can do the following to
read the file from comment #0:

f = fopen('ISO-8859.csv', 'r', 'n', 'iso-8859-1');
str = fgets(f);
str(end) = '';
fclose(f);

regexprep(str, '1', '2')


The output is:

ans =   2T2(°C)  
>> double(str)
ans =

    32    32    49    84    49    40   194   176    67    41    32    32


Should we make this bug about choosing a fallback option for invalid UTF-8 so
that specifying the input encoding isn't necessary for files encoded in
ISO-8859-1?
