international character string works as string argument but not inparser

[Willem J. Atsma]

Thanks for the rapid reply. Here are some examples:


----------------------------------------------------------------------
octave:1>data_index.('Québec') = 1
data_index =
{
  Québec =  1
}
octave:2>fieldnames(data_index)
ans =

{
  [1,1] = Québec
}
----------------------------------------------------------------------

So the accented character is preserved. Everything seems to work. It only gives trouble when 
going through the commandline directly. 


Thanks!

Willem

That doesn't work for me.  I see

  octave:1> data_index.('Qu?bec') = 1
  error: invalid structure field name `Qu?bec'

After doing something like

  data_index.('Québec') = 1;

what does

  data_index

or

  fieldnames (data_index)

show you?  Is the é in the field name preserved?

Yes, Octave is not yet 8-bit clean.  It will take a lot of work to make it 8-bit clean, so I consider this a "probably won't fix for quite some time" bug.
