----------------------------------------------+-----------------------------
 Accented characters in EIA-708 closed captions (on ATSC stations) do not
 show up correctly.  They appear as boxes.

 The underlying problem is sign extension which occurs when characters are
 converted from char to ushort in the CCtableG1 array.  (For example, the
 character 0xE0 becomes 0xFFE0 instead of 0x00E0 when it is converted.)

 Attached is a patch which corrects this problem by adding casts to uchar
 into the definition of CCtableG1.
