Format of closed captions in premier pro

Hi Stan, Regarding formatting, you helped me over the weekend create a 608 Caption so I could export in SCC. That worked fine and I fixed my line lengths. Now I, too, have a format/font question. I chose a caption style that used arial, I'm pretty sure. When I re-import the SCC file into PP, I chose no style (choosing the same style I had exported in moved captions below that had been placed at the top of the screen to avoid covering titles) and it imported in a larger different font. I don't care about that, except that it seems that in a few instances, the bottom line had been slided over rather than centered. And in some cases, apostrophes became white squares. Is there anything I can do to prevent this? I see you mention that the size of the font is controlled ultimately by the viewer. Is this something that can be adjusted by PBS when they import them? Did I format something wrong so this is happening?  Thanks Joe.

Closed Caption 608 is limited to 32 characters per line; 708, 42. You actually can't change font size - that is left to the viewer, and will also be limited.

Closed captions on one line are challenging.

Since you see a font size option, I assume you have some type of caption stream other than 608/708? And single/multi-line formatting can be challenging in any of the formats.
