Transcription functions generate character-encoding errors

[jmacdotorg]

Probably gotta work in some :utf8 encoding layers when setting up output file handles.

Lots of these errors:

[error] Caught exception in IFComp::Controller::Play->transcribe "Wide character in subroutine entry at /home/ifcomp/ifcomp/IFComp/lib/IFComp/Controller/Play.pm line 98."

[error] Caught exception in IFComp::Controller::Play->transcribe "malformed UTF-8 character in JSON string, at character offset 747 (before "\x{eb}'s line, and h...") at /home/ifcomp/ifcomp/IFComp/lib/IFComp/Controller/Play.pm line 98."
