# Exercise screen-redraw.c bidirectional-isolate handling. When the client is
|
|
# UTF-8 and its terminal has the Bidi capability, each drawn span is wrapped in
|
|
# directional isolate characters (U+2066 .. U+2069) so a bidi terminal does not
|
|
# reorder pane contents across borders (the REDRAW_ISOLATES path).
|
|
#
|
|
# The Bidi capability is added with terminal-overrides before the client
|
|
# attaches, so the attached client picks it up. The isolate characters appear in
|
|
# the captured output around each span.
|
|
#
|
|
# Run with GENERATE=1 to (re)create the golden files.
