making utf8-clean CPAN distributions

I'm looking for help from you guys on an important forward-looking question.

What I would like to do is create my CPAN module distributions such 
that all of the files in each distro, code and documentation and 
tests and logs alike, are properly UTF-8 encoded, and do this in such 
a way that no modern Perl distributions or the automated CPAN tools 
will break.  Note that my modules in question are so bleeding edge 
that I don't expect to have any legacy users yet to worry about 
breaking compatability with.  It's a given that I'm using UTF-8, 
which is supposed to be network safe and only have only a single 
byte-order; I don't plan to touch UTF-16 or any other variations.

For tools, I have on my machine Mac OS X 10.3.6 (operating system), 
and BBEdit 8.0.3 (text editor), both of which are fully Unicode 
aware.  I'm also using the latest Perl, version 5.8.6, compiled 
myself with the OS-bundled dev tools such as GCC 3.3 etcetera.  I am 
making the distributions formally require 5.008.

0. For my main question, is distribution as Unicode files a good idea 
at all currently, though few if any people do it?

The following questions only apply if the answer to the above is "yes".

1. BBEdit gives me an option to have a byte-order mark in UTF-8 files 
(that happens to be 3 octets long I think), with the recommendation 
being to use it; I also have the choice not to, which makes the file 
more similar to many other ASCII-like encodings.  So should I save 
the files with the BOM or without?

2. I am given a separate option to use either Unicode linebreaks or 
one of Unix/Mac/Win; all 4 are given as options to use with a Unicode 
encoding.  In my own tests, Perl 5.8 complained when the Unicode line 
break was used with UTF8, but not the Unix line break (I was not, 
however, using any special pragmas).  So should I use the Unicode 
linebreak or the Unix linebreak, assuming the former can be made to 
work?

2.1 Will the addition of "use utf8" on the first line of a Perl file 
cause Perl to accept files with Unicode line breaks?

3. Can a "use utf8" be put anywhere besides the first line of a file? 
What if I customarily put POD on the first few lines and the package 
declaration beneath it?  Also, in a script file, which goes first, 
the #!perl or the use-utf8?

4. What about plain POD files?  Since they contain no POD, will POD 
extractors know what to do since I can't put the use-utf8 in them?

5. Would the CPAN compare utility adapt to encoding changes, or would 
it consider an otherwise-identical file with different encodings to 
consist of one very large change?

6. In general, would anything on CPAN break?  What about the automated testers?

7. Are there any other common issues that I should be aware of, and 
if so then what?

AFAIK, Perl 6 is going to expect its code files to be Unicode by 
default?  I know Larry said that some Unicode characters would be 
used by the language grammar.

Thanks for any input you can give.
