    d2 = "123\n".b + "\x1a\xe8\xba\b".b + "\n789\n".b
    
    File.binwrite('1.txt', d2)
    
    p File.binread('1.txt').each_line.to_a # => ["123\n", "\x1A\xE8\xBA\b\n", "789\n"]
    
    
    
    p File.foreach('1.txt').to_a           # => ["123\n"]
    
    Encoding.default_external = Encoding::UTF_8
    p File.foreach('1.txt').to_a           # => ["123\n"]
    
    Encoding.default_external = Encoding::ASCII_8BIT
    p File.foreach('1.txt').to_a           # => ["123\n"]



run above code on windows, File.foreach.to_a just return 1 row.
run on mac and linux, that's correct, return 3 rows.
