示例 #1：

# Ruby Program of Integer chr function
  
# Initializing the numbers 
num1 = 65
num2 = 66
num3 = 97
num4 = 245
   
# Prints the chr 
# after encoding 
puts num1.chr
puts num2.chr
puts num3.chr
puts num4.chr(Encoding::UTF_8)

输出：

A
B
a
õ

示例 #2：

# Ruby Program of Integer chr function
  
# Initializing the numbers 
num1 = 119
num2 = 68
num3 = 89
num4 = 255
   
# Prints the chr 
# after encoding 
puts num1.chr
puts num2.chr(Encoding::UTF_8)
puts num3.chr
puts num4.chr(Encoding::UTF_8)

输出：
