How To Install libxml-um-perl on Debian 9

Introduction

In this tutorial we learn how to install libxml-um-perl on Debian 9.

What is libxml-um-perl

libxml-um-perl is:

The XML::UM module provides methods to convert UTF-8 strings to any XML encoding that XML::Encoding supports. It creates mapping routines from the .xml files that can be found in the maps/ directory in the XML::Encoding distribution. Note that the XML::Encoding distribution does install the .enc files in your perl directory, but not the.xml files they were created from. That’s why you have to specify $ENCDIR as in the SYNOPSIS.

This implementation uses the XML::Encoding class to parse the .xml file and creates a hash that maps UTF-8 characters (each consisting of up to 4 bytes) to their equivalent byte sequence in the specified encoding. Note that large mappings may consume a lot of memory!

Future implementations may parse the .enc files directly, or do the conversions entirely in XS (i.e. C code).
