如何使用PHP生成带有重音字符的CSV文件？

Accented characters like enie (ñ) are difficult to handle when generating CSV files. The tendency is one might end up having different and unexpected characters.

In my case, the CSV file I generated got a \1\1 instead of ñ. Thus instead of having Niño it got Ni\1\1o.

Is this even possible to fix? How to generate a CSV file with accented characters using PHP?

You can encode the data check

http://php.net/manual/en/function.mb-convert-encoding.php

You can try this

header('Content-Encoding: UTF-8');
header('Content-type: text/csv; charset=UTF-8');
header('Content-Disposition: attachment; filename=Customers_Export.csv');
echo "\xEF\xBB\xBF";
