[fpc-pascal] Reading and writing char

[Thomas Young]

Thank you for the article. It was very helpful.

Why is it I can read and write a string that contains characters in the upper 128 but can't read & write them as individual char?

Specifically I need to read the copyright (169), trademark (170) and registration (168) characters. Any suggestions on how I can do this?
