This most likely is caused by a missing character in the font.
Fonts from nerdfonts can fix this problem.
Post installation the appropriate environment needs to be aware of the font.
This can be mitigated individually on a terminal emulator level, see the FAQ for more information.
This sadly seems to be an issue that can not be mitigated easily, more information can be found here.
mouse_mode is turned on zellij handles these events, zellij provides an
escape mechanism in the form of the
SHIFT Key, once it is pressed zellij lets
the terminal handle selection, clicking on links, copying, scrolling.

This is a known problem which mostly occurs in specific terminal emulators under Linux/OS X such as GNOMEs default Terminal, terminator, and more.
A workaround for this was added in zellij > 0.24.0 and enables the user to
specify a custom command that copies selected text to the system clipboard.
Refer to lines containing "copy_command" from the output of
zellij setup --dump-config.
This can happen in some terminal emulators (eg. Xterm). It can be remedied either on the terminal emulator side by getting the terminal emulator to send
^? instead of
^H, or on the Zellij side by remapping ctrl-h to some other key. Here's an example fix in xterm: http://www.hypexr.org/linux_ruboff.php
