Progress: Continue string and convert changes, fixing bugs.

Fix some bitwise operation comparison mistakes.

I used the wrong ASCII reference for the '@' and possibly others.
This broke octal representation.

This improves handling of Unicode characters in the safely print functions.
It seems there are Control characters with widths greater than one.
This complicates the code but what must be done, must be done.

Begin adding back some of the color print functions as f_print_color() etc...
There are still more to create.
