3270cg encoding

Description
The x3270 fonts use a proprietary encoding scheme called 3270cg.

In the tables below, each cell has two lines, both of which are optional:
 * The special EBCDIC code or OIA symbol that it is used to display, or the Unicode equivalent code point
 * The glyph that is displayed

Note: All 3270 fonts implement the line-drawing code points. Only 3270 and 3270bold implement the APL code points.
