-----------------------------------------------
**Never** output unknown binary data directly into a terminal.
Terminals have a single channel for both data and control. Certain bytes
are control codes. Some of these control codes are of arbitrary length, so
if the binary data you output into the terminal happens to contain the starting
sequence for one of these control codes, the terminal will hang waiting for
the closing sequence. Press :kbd:`ctrl+shift+delete` to reset the terminal.
kitty is not able to use my favorite font?
