Happy Holidays,

Here are some suggestions in the form of a uni-diff patch (note that I've
introduced some line breaks).
BTW, I think there was a perli18n.pod doc distributed with an earlier
version of perl.

<b>Q1. I think that I'm a clever programmer. What's so hard about
internationalization?</b>
<p>
-A1. Internationalizing a product involves issues about program design,
application language features, cultural practices, fonts and often legacy
clients. Most programmers face a rude awakening when first internationalizing
an application after a career of only ASCII. Little details often become big
headaches. The most important thing you can do is start your international
design early.

<b>Q18. Is there an EBCDIC-safe transformation of Unicode?</b>

A18. Yes. UTF-EBCDIC stands for EBCDIC-friendly Unicode (or UCS)
Transformation Format.

Where to Use UTF-EBCDIC?
<p>
UTF-EBCDIC is intended to be used inside EBCDIC systems or in closed networks
where there is a dependency on EBCDIC hard-coding assumptions. It is not meant
to be used for open interchange among heterogeneous platforms using different
data encodings. Due to specific requirements for ASCII encoding for line
endings in some Internet protocols, UTF-EBCDIC is unsuitable for use over the
Internet using such protocols. UTF-8 or UTF-16 forms should be used in open
interchange.
