{utf-8}

Hewlett-Packard, in its Master Symbol List (MSL), has a very simple scheme
for naming all these odd symbols (U+2500 and following).
For example, ╓ is "Right 1, down 2"; ╞ is "Right 1, vertical 2"; ╪ is
"Horizontal 2, vertical 1" (not so concise!), and ╦ is "Horizontal 2, down
2".
Using the abbreviations "Vert." and "Horiz." can condense the names.
