fix(cea): Fix some CEA-608 special characters.

The quotes in the Spanish/French character set should be the curly
quotes, not the straight ASCII quotes.  Also, the last entries in the
Portuguese/German should be box-drawing characters; the dash and one
of the vertical bar characters should match these to form contiguous
boxes.
