A small artist adjunct
The command ‘aa2u’ converts simple ASCII art line drawings in
the {active,accessible} region of the current buffer to Unicode.
Command ‘aa2u-rectangle’ is like ‘aa2u’, but works on rectangles.
Example use case:
- M-x artist-mode RET
- C-c C-a r ; artist-select-op-rectangle
- (draw two rectangles)

Much easier on the eyes now!
Normally, lines are drawn with the ‘LIGHT’ weight. If you set var
‘aa2u-uniform-weight’ to symbol ‘HEAVY’, you will see, instead:
┏━━━━━━━━━━━━━━━┓
┃ ┃
┃ ┏━━━━━━━╋━━┓
┃ ┃ ┃ ┃
┃ ┃ ┃ ┃
┃ ┃ ┃ ┃
┗━━━━━━━╋━━━━━━━┛ ┃
┃ ┃
┃ ┃
┃ ┃
┗━━━━━━━━━━┛
To protect particular ‘|’, ‘-’ or ‘+’ characters from conversion,
you can set the property ‘aa2u-text’ on that text with command
‘aa2u-mark-as-text’. A prefix arg clears the property, instead.
(You can use ‘describe-text-properties’ to check.) For example:
┌───────────────────┐
│ │
│ |\/| │
│ ‘Oo’ --Oop Ack! │
│ ^&-MM. │
│ │
└─────────┬─────────┘
│
"""""""""
Command ‘aa2u-mark-rectangle-as-text’ is similar, for rectangles.
Tip: For best results, you should make sure all the tab characaters
are converted to spaces. See: ‘untabify’, ‘indent-tabs-mode’.
