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

[Dan Sebald]

Follow-up Comment #3, bug #52681 (project octave):

There is a routine called textread() that comes close, but it still has some
flakiness.  For example, the following gives the appearance of working:


octave:33> [a b c] = textread ('p1.txt',"%s %s %s")
warning: range error for conversion to character value
warning: called from
    textread at line 162 column 14
a =
{
  [1,1] = País
  [2,1] = Chipre
  [3,1] = Dinamarca
  [4,1] = Atenas
  [5,1] = España
  [6,1] = 
}

b =
{
  [1,1] = Capital
  [2,1] = Nicosia
  [3,1] = Copenhague
  [4,1] = Grecia
  [5,1] = Madrid
  [6,1] = 
}

c =
{
  [1,1] = Población
  [2,1] = 300000
  [3,1] = 509861
  [4,1] = 745414
  [5,1] = 3250645
  [6,1] = 
}


but try reading just the header, and the UTF seems lost:


octave:34> [a b c] = textread ('p1.txt',"%s %s %s", 1)
warning: range error for conversion to character value
warning: called from
    textread at line 162 column 14
warning: range error for conversion to character value
warning: called from
    textread at line 236 column 9
a =
{
  [1,1] = Pas
}

b =
{
  [1,1] = Capital
}

c =
{
  [1,1] = Poblacin
}


But this sort of works:


octave:38> [a b c] = textread ('p1.txt',"%s %s %d", "headerlines", 1)
warning: range error for conversion to character value
warning: called from
    textread at line 162 column 14
a =
{
  [1,1] = Chipre
  [2,1] = Dinamarca
  [3,1] = Atenas
  [4,1] = España
  [5,1] = 
}

b =
{
  [1,1] = Nicosia
  [2,1] = Copenhague
  [3,1] = Grecia
  [4,1] = Madrid
  [5,1] = 
}

c =

   300000
   509861
   745414
  3250645
        0
