"An exception to this is in Line Graphics Enable mode, which causes code
points 0xC0 to 0xDF inclusive[1] to have the 8th column repeated as the
9th. These code points cover those box drawing characters which must
extend all the way to the right side of the glyph box. For this reason,
placing letter-like characters in code points 0xC0-0xDF should be
avoided. The box drawing characters from 0xB0 to 0xBF are not extended,
as they do not point to the right and so do not require extending. "
