Point this script to your transcripts, and it returns
to the terminal the unique set of characters in those
files (combined).

These files are assumed to be comma delimited,
with the transcript being the third field.
These files are assumed to be csv, with the transcript being the third field.

The script simply reads all the text from all the files,
storing a set of unique characters that were seen
along the way.
