@ -112,8 +112,17 @@ The following keypresses are recognized (and are also available from the menu):
* **Ctrl-R**: Restart the demo.
* **q**: Quit.
Benchmarking should be performed using **-c** to get a well-defined PRNG seed.
JSON output via **-J** will probably be useful.
# BUGS
Certain demos (especially **mojibake** and **allglyph**) heavily exercise the
font rendering stack. If your font or rendering engine draws glyphs with width
different from that reported by the standard library's **wcwidth(3)**,
Notcurses will have an incorrect notion of cursor placement, leading to
undesirable behavior.
