示例 #1：

# Ruby code for Symbol.encoding() method
  
# declaring Symbol 
a = :aBcDeF
  
# declaring Symbol
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"
  
  
# encoding form 
puts "Symbol a encoding form : #{a.encoding}\n\n"
puts "Symbol b encoding form : #{b.encoding}\n\n"
puts "Symbol c encoding form : #{c.encoding}\n\n"

输出 ：

Symbol a : aBcDeF

Symbol b : äöü

Symbol c : ABCDEF



Symbol a encoding form : US-ASCII

Symbol b encoding form : UTF-8

Symbol c encoding form : US-ASCII

示例 #2：

# Ruby code for Symbol.encoding() method
  
# declaring Symbol 
a = :geeks
  
# declaring Symbol
b = :"\u{e5 f6 f3}"
  
# declaring Symbol
c = :GEEKS
  
# Symbol 
puts "Symbol a : #{a}\n\n"
puts "Symbol b : #{b}\n\n"
puts "Symbol c : #{c}\n\n\n\n"
  
  
# encoding form 
puts "Symbol a encoding form : #{a.encoding}\n\n"
puts "Symbol b encoding form : #{b.encoding}\n\n"
puts "Symbol c encoding form : #{c.encoding}\n\n"

输出 ：

Symbol a : geeks

Symbol b : åöó

Symbol c : GEEKS



Symbol a encoding form : US-ASCII

Symbol b encoding form : UTF-8

Symbol c encoding form : US-ASCII
