Example #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)

Output:

A
B
a
õ

Example #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)
