Exact steps to reproduce the issue

Clone the repo, enable nerdfonts in the makefile

O_NERD := 1  # support icons-nerdfont

and compile with LDLIBS="-L/opt/homebrew/opt/ncurses/lib/" make.

Some files (with certain icons it appears) have duplicate initial letters as seen in the screenshot below:

as soon as I select the makefile it will also have the duplicate initial letter:

I have done some testing, this seems to also happen with O_EMOJI is set to enabled:

but not with O_ICONS enabled:

I have peeked into the source code to find what is different between those options, but did not find a convincing clue.

I have also checked with kitty and alacritty, they both face the same problem.

These are the dynamic libs used by nnn:

 x otool -L ./nnn
./nnn:
	/usr/lib/libedit.3.dylib (compatibility version 2.0.0, current version 3.0.0)
	/opt/homebrew/opt/ncurses/lib/libncursesw.6.dylib (compatibility version 6.0.0, current version 6.0.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1319.0.0)
