brick FAQ

=========

|
|
|
* Q: Why doesn't brick get my Ctrl-arrow key events?
|
|
* A: Your terminal emulator probably isn't sending the expected
|
|
sequences. For example, OS X's Terminal.app does not do this by
|
|
default and requires configuration to make it work. See also:

|
|
|
|
* Q: Why do some emojis mess up the layout?
|
|
* A: For wide characters to be displayed correctly, [vty]'s
|
|
determination of the character width and the user's
|
|
terminal emulator's determination of the character width
|
|
must match. Unfortunately, every terminal emulator
|
|
calculates this differently, and none correctly follow
|
|
the Unicode standard.
|
|
The issue is further complicated by Unicode combining
|
|
characters and releases of new versions of the Unicode
|
|
standard.
|
|
|
|
As a result, the current recommendation is to avoid
|
|
use of wide characters due to these issues.
|
|
If you still must use them, you can read [vty]'s
|
|
documentation for options that will affect character
|
|
width calculations.
