Question

I have a string containing urdu characters like ‘بجلی’ this is a 1×4 array. I want to save this to a file, which would be viewed externally. Although this string doesnt display in the main Command Window, but variable ‘str’ does hold it. When I save this using fprintf(fid, str), and open that file in notepad there appear ‘arrows’ instead on the original characters. I can easily paste my characters into notepad manually. Where is the problem?

Answer 1

You need to use fwrite() not fprintf():

fid = fopen('temp.txt', 'w');

str = char([1576, 1580,  1604, 1740, 10]);

encoded_str = unicode2native(str, 'UTF-8');
fwrite(fid, encoded_str, 'uint8');

fclose(fid);

verified with:

perl -E "open my $fh, q{<:utf8}, q{temp.txt}; while (<$fh>) {while (m/(.)/g) {say ord $1}}"
1576
1580
1604
1740
