Comment 20 for bug 1709710

Pushed a branch:

http://git.evergreen-ils.org/?p=working/OpenSRF.git;a=shortlog;h=refs/heads/user/berick/lp1709710-smarter-chunk-length-and-bytes

Includes sign-offs for the original 2 commits.

Adds a new commit to calculate string byte counts instead of length in the Perl chunking/bundling code. Note, after a little more reading, decided to go with the newer recommended approach of counting bytes via length(Encode::encode_utf8($str)). For reference, https://perldoc.perl.org/bytes.html and 'perldoc -f length'.

This is a slightly larger change than I wanted to rubber-stamp for myself, so leaving here for additional sign-off.
