b = :"\u{e4 f6 fc}"
  
# declaring Symbol
c = :ABCDEF
  
# Symbol 
puts "Symbol a : #{a}\n\n"
puts "Symbol b : #{b}\n\n"
puts "Symbol c : #{c}\n\n\n\n"
  
  
# next form 
puts "Symbol a next form : #{a.next}\n\n"
puts "Symbol b next form : #{b.next}\n\n"
puts "Symbol c next form : #{c.next}\n\n"

输出 ：

Symbol a : aBcDeF
