Hi there

Are you a Unicode fan?

Personally, I am not. The reason is that I still struggle to get my head around it. During my early days of learning, I never got the opportunity to work with Unicode. So far, I have never had to deal extensively with Unicode characters. There is so much information available on the internet. I remember, a long time ago, I was dealing with the well-known warning Wide character in print. After a quick search, I came across this explanation by Dave Cross. I have kept it bookmark for future reference. I know am repeating myself here as I remember talking about in an earlier weekly newsletter. It is worth sharing with readers again and again.

However, there is another reason why I am talking about it today. Let me share gem of an article by David Cantrell. The article gives us very deeps knowledge about Unicode, specially for a Perl developer. It has cleared most of my doubts, so a big thanks to David for such a great article. It also introduced me to a new word, Mojibake. A friend of mine on Facebook, suggested a CPAN module, Test::Mojibake which is very handy. I wish there was dedicated book on Perl and Unicode. Having said that, I found this Wikibook on the subject, you may want to explore it.

I came across a YouTube video that explains Unicode in terms that any lay-person can easily understand. I loved it the way it is explained in a casual way. The guy in the video makes it so simple.

Let's talk about regexes in Perl.

I am sure you have used regexes in Perl at some point in your career. A few days ago, I found out a clever use of regexes shared by Abigail. The use of //g in list context. It completely blew me away. Later someone pointed me to the official Perl documentation talking about it. If you are curious to know more about it then I would suggest you take a look at his blog post.

Enjoy rest of the newsletter.
