For ruby (at least MRI), any string that can have a special syntactic meaning appears to be ASCII characters.(parse.y is written using functions defined in the link below)

https://github.com/ruby/ruby/blob/a8812080c4977c2731e8ff1b129b59d236bc12e3/include/ruby/ruby.h#L2220

In that sense, full-width spaces are not given any particular syntactic meaning, so it seems that ruby's parsing was working as one string or .(So finally array1 appears to have been parsed as an array of length 1 called ["you"])

Other than that, it's just as someone else explained.

array1=%w[Yes]
array2 = ["A", "I", "U"]
puts array1 == array2
# = > true
