Determine terminal display width (columns) of Ruby strings via FFI bindings to libc's wcswidth() function.
See unicode/display_width for a Ruby-only unicode data based approach.
Usage
require 'wcswidth/kernel_method'
full width chars
wcswidth("！") # => 2 wcswidth("一") # => 2
single width chars
wcswidth("A") # => 1 wcswidth("·") # => 1
zero width chars
wcswidth("ֿ") # => 0 wcswidth("\0") # => 0
control chars
wcswidth("\x01") # => -1 wcswidth("\n") # => -1
Without opting in for wcswidth/kernel_method it is Wcswidth.of("string")
