Characters:

Single line

• ASCII code 191 = ┐ ( Box drawing character single line upper right corner )
• ASCII code 192 = └ ( Box drawing character single line lower left corner )
• ASCII code 193 = ┴ ( Box drawing character single line horizontal and up )
• ASCII code 194 = ┬ ( Box drawing character single line horizontal down )
• ASCII code 195 = ├ ( Box drawing character single line vertical and right )
• ASCII code 196 = ─ ( Box drawing character single horizontal line )
• ASCII code 197 = ┼ ( Box drawing character single line horizontal vertical )
• ASCII code 217 = ┘ ( Box drawing character single line lower right corner )
• ASCII code 218 = ┌ ( Box drawing character single line upper left corner )
• ASCII code 179 = │ ( Box drawing character single vertical line )
• ASCII code 180 = ┤ ( Box drawing character single vertical and left line )

Double line

• ASCII code 185 = ╣ ( Box drawing character double line vertical and left )
• ASCII code 186 = ║ ( Box drawing character double vertical line )
• ASCII code 187 = ╗ ( Box drawing character double line upper right corner )
• ASCII code 188 = ╝ ( Box drawing character double line lower right corner )

• ASCII code 205 = ═ ( Box drawing character double horizontal line )
• ASCII code 206 = ╬ ( Box drawing character double line horizontal vertical )

Shading

• ASCII code 176 = ░ ( Graphic character, low density dotted )

@dsample you have proved that it is possible to use extended ASCII codes to produce the box drawing characters by responding to this gist, but how have you entered the characters?

@dsample

XTerm terminal

Ohh so XTerm it was. IIRC, I used that one last year when I was exploring a Linux distro, and I think it got UTF-16, so it makes sense it'd work.
For context, I started university not so long ago and I hadn't really used any Linux distro as deeply as I'm doing now, that's why I'm talking about recent things.
