#9582 closed Patch - Bug Fix (fixed)

CEA-708 extended characters do not display

Description

CEA-708 extended characters (from the G2 table) do not get displayed. This is because the codepoint for EXT1 is set to 0x01 in cc708decoder.cpp, even though it should be 0x10. The attached patch corrects this problem, and also corrects the unicode codepoints of several of the extended characters.

After making these changes, all extended characters from the PBS test material (​http://ncamftp.wgbh.org/DTV/CEA%20test%20material/Iteration_1/) now display correctly. I've also tested on some other shows to make sure that the patch doesn't break anything.
