[Octave-bug-tracker] [bug #52681] Bad reading for UTF-8 characters with fscanf()

[Dan Sebald]

Follow-up Comment #5, bug #52681 (project octave):

The issue is mainly, I think, that reading data from a file always casts the
read quantity to the specified format.  Once past that, the goal seems more
achievable.  Here's the shortest amount of code


fid = fopen('p1.txt', 'r');
d = fread(fid, 'uint8');
fclose(fid);
cstr = char(d');
[header] = textscan(cstr, '%s', 3){1};
[pais capital poblacion] = deal(textscan (c, '%s%s%d', 'headerlines', 1){:});


and some longer amount of code:


fid = fopen('p1.txt', 'r');
d = fread(fid, 'uint8');
fclose(fid);
c = char(d');
[pais capital poblacion] = strread(c, '%s %s %s');
header = {pais{1} capital{1} poblacion{1}};
pais = pais(2:end);
capital = capital(2:end);
poblacion = cellfun('str2num', poblacion(2:end));


Note that the translation


c = native2unicode(d');


doesn't seem necessary.  I suppose the usefulness of the native2unicode()
comes in when it is something other than the Octave-assumed UTF-8.
