How To Install libcatalyst-plugin-unicode-perl on Ubuntu 18.04
Introduction
In this tutorial we learn how to install libcatalyst-plugin-unicode-perl on Ubuntu 18.04.
What is libcatalyst-plugin-unicode-perl
libcatalyst-plugin-unicode-perl is:
At request time Catalyst::Plugin::Unicode decodes all params from UTF-8 octets into a sequence of logical characters. On response, encodes body into UTF-8 octets.
Note that this plugin tries to autodetect if your response is encoded into characters before trying to encode it into a byte stream. This is bad as sometimes it can guess wrongly and cause problems.
As an example, latin1 characters such as é (e-accute) will not actually cause the output to be encoded as utf8.
Using Catalyst::Plugin::Unicode::Encoding (part of Catalyst 5.90042, packaged in libcatalyst-perl) is much more recommended, and that also does additional things (like decoding file upload filenames and request parameters which this plugin does not).
This plugin should be considered deprecated, but is maintained as a large number of applications are using it already.
Catalyst is an elegant Model-View-Controller web application framework written in Perl.
