Glad to help!

when working with UTF8, wide character warnings seem to appear for no reason at times, when everything is working properly, and sometimes I get the uninitialized errors that are also extraneous ... I'd rather get useless warnings.

While I agree that when building strings for output, the "uninitialized" warnings can often be turned off (no warnings 'uninitialized';, limited to the scope where it's needed), the UTF-8 / wide character warnings are actually useful and are pointing to the fact that something is wrong, even if it may appear to be "working beautifully". For example, at my console, I can do this:

$ perl -le 'print "\N{U+263A}"'
Wide character in print at -e line 1.
☺

Since the smiley was printed correctly, it appears to be working. But the fact that it worked is only because my terminal's encoding happened to match the encoding Perl used. So if you're getting these warnings, likely you've still got an encoding issue somewhere, and it might come back to bite you later. It would probably be helpful if you can reduce the issue down to an SSCCE, then you could post it as a new question here to get help with it.

even though the "use utf8;" pragma is in place

The utf8 pragma only tells Perl that the source code is encoded in UTF-8. It doesn't change the encoding of STDIN, STDOUT, etc. - for that, you could use the open pragma, e.g. use open qw/:std :utf8/;.
