feat: Added the pure chars and fixed the duplicate text

[PeterStaar-IBM]

features:

1. export character level information
2. fix parameter-operator confusion in stream
3. do sanitization properly of rotated strings (visualization script still needs to be updated to view rotated text properly. The rotated boxes come out nicely.)
