Are all binary file ASCII based
I am trying to research simple thing, but not sure how to find.
I was reading PDF Stream filter, and PDF document specification, it is written in Postscript, so mostly ASCII.
I was also reading one compression algorithm "LZW", the online examples mostly makes dictionary with ASCII, considering binary file only constitute only ASCII values inside.
My questions :
1. Does binary file (docx, excel), some custom ones are all having ASCII inside
2. Does the UTF or (wchar\_t), also have ASCII internally.
I am newbie for reading and compression algorithm, please guide.
