Use Perl to create the implementation code for the specified encoding format (such as utf-8) file _perl

This allows some characters (especially wide characters) to be displayed incorrectly, which is no longer utf-8 format.

Solution:
When you open the output file, you specify the encoding format, and there is no garbled situation after the output file is opened.

The normal default open output file:

Copy Code code as follows:

Open (OUTPUT, ' >>output.txt ') | | Die "Can not open the file: $!";

Defines the specified encoding format file (or becomes a file that uses Perl to create a specified encoding format):

Copy Code code as follows:

Open OUTPUT, ">:encoding (Utf-8)", "output.txt";
Print OUTPUT $something;
Close OUTPUT;
