Gnuplot reading not locale encoding file - encoding

Question

I want to plot data of an ISO_8859_1 encoded file (two columns of numbers). Those are the first 10 data points of the file:
#Pe2
1 0.8000
2 0.8000
3 0.8000
4 0.8000
5 0.8000
6 0.8000
7 0.8000
8 0.8000
9 0.8000
10 0.8000
The original file has 15000 data points. I create this data with MATLAB, specifically setting ISO_8859_1 encoding, so I am sure that that's the encoding. This is a snippet of the matlab code:
slCharacterEncoding('ISO-8859-1'); %Instruction before writing anything to the file.
fprintf(fileID,' %7d %7.4f',Tempo(i),y(i)); %For loop in this instruction
fprintf(fileID,'\r'); %Closing the file
fclose(fileID);
This is the script that I run. This file is encoded with the default Windows txt files encoding:
set encoding iso_8859_1
set terminal wxt size 1000,551
# Line width of the axes
set border linewidth 1.5
# Line styles
set style line 1 lc rgb '#dd181f' lt 1 lw 1 pt 0 # red
# Axes label
set xlabel 'tiempo'
set ylabel 'valor'
plot 'Pe2.txt' with lines ls 1
This is the output of the gnuplot console when I run the script. After that I input "show encoding":

nominal character encoding is iso_8859_1
however LC_CTYPE in current locale is Spanish_Spain.1252

If I open the file, make some change undo the change and save the file, gnuplot plots the file. I guess that it's because it saves it with local encoding which is the one gnuplot uses to read files.
How do I plot files with gnuplot which are not with the local encoding format?
I also have what it seems to be a similar problem when I output a file with VS2010Css. If I don't specifically set the culture with:
Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo("en-US");
Thread.CurrentThread.CurrentCulture = CultureInfo.GetCultureInfo("en-US");
I am not able to save a file wich gnuplot is able to plot. I believe that this last problem is because of the "," and the "."
In Css I save the files with this:
StreamWriter Writer = new StreamWriter(dir + #"\" + + (k+1) + "_" + nombre + extension);
Writer.WriteLine("#" + (k+1) + "_" + nombre);
Writer.WriteLine();
Writer.WriteLine("{0,32} {1,32}", "#tiempo", "#valor");
for (int i = 0; i < tiempo.GetLength(0); i++)
{
Writer.WriteLine("{0,32} {1,32}", tiempo[i].ToString(), valor[i, k]);
}
Thank you.

Your file has only carriage returns (\r 0xd) as line breaks which doesn't work with gnuplot. You must use only line feed (\n 0xa), but \r\n does also work.
