将unicode字符串写入Matlab中的文件 [英] Write unicode strings to a file in Matlab

问题描述

我有一个字符串，其中包含诸如'بجلی'之类的乌尔都语字符，这是一个1x4数组.我想将其保存到文件中，以从外部查看.尽管此字符串未显示在主命令窗口中，但变量'str'确实将其保存.当我使用fprintf(fid，str)保存此文件，并在记事本中打开该文件时，原始字符上会出现箭头".我可以轻松地将我的角色手动粘贴到记事本中.问题出在哪里?

I have a string containing urdu characters like 'بجلی' this is a 1x4 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?

推荐答案

您需要使用fwrite()而不是fprintf():

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);

已验证:

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