unicode line folding

[l]

Hi,

"/\s*/" based word wrapping is not working with Japanese context.
Because usually Japanese string doesn't contain any white spaces in
context.

I added line folding code (based on Text::LineFold). It works fine
with English and Japanese context.

Hey there—

I'm so sorry I haven't replied to this... I truly don't understand how I didn't see it, as I've replied to other GitHub issues in the meantime. But this is the first time I'm seeing this patch.

You've likely moved on now, but in case you haven't, I'll be happy to merge given a couple things:

1. You need to add test cases with CJK text. I, alas, am not qualified; 大学で、私は日本語を勉強しました。しかし、すべてを忘れてしまった。。:-) Otherwise, I'd merge this, even if you have given up.
2. The SYNOPSIS as rewritten suggests that setting all that stuff is required. The synopsis for a CPAN module is supposed to just show the minimal required to usefully use a module. I can rewrite it if you like if you want to do the test cases.

Hi treyharris,

Thanks for reply. According to your suggestion...

1. Added test case for CJK text.
   It looks too much, but I think it's good for example. The text is taken from perlintro.
2. Modified $shoulebe literal for 1st test case
   After commit 9a7d97d, line folding is performed based on Unicode Line Breaking Algorithm (via Unicode::LineBreak). So, new result does not exactly match with previous one. If you don't like this behavior, we need more discussion.

This looks great, and is probably a much better version of a patch I have applied locally.
