PowerShell<->Perl: Reading UNICODE files

Problem Statement:
Recently, I faced a tricky situation at work. I had a CSV file generated out of a PowerShell script. I was trying to read the CSV file and generate a graph using Perl TK module. To my surprise, no value from the CSV file got plotted on the graph! Why would this happen?

Reason:
After some tussle, I found that, this was because PowerShell generated the CSV file in a UNICODE format. PERL opens the Unicode file but can’t recognize the content. This is because “Unicode format is not a character encoding”. Hence the issue!

Resolution:
In such cases, one needs to open the Unicode files using any other Perl supported encoding format. Say, we open the file as:
Open (FH, “<:utf-8”, “filepath”);
OR
Open (FH, “<:encoding(utf-8)”, “filepath”);

Thus, Unicode text files are read exactly the same way that other files are read: by specifying a text encoding.
