Subject: [PATCH] Fix missing exit and incorrect comments in unicode-testscript

Add missing 'exit 1' when $HOME/trojan-source directory is not found,
which previously caused the script to continue and fail confusingly.
Fix swapped exit-code comments in process_file and correct comments
that referenced unicode-show when the tested command was sanitize-string.
