Characters and Strings to ASCII Values[edit]
Swift[edit]

// First, set up required extension for Character
extension Character {
var isAscii: Bool {
return unicodeScalars.first?.isASCII == true
}
var ascii: UInt32? {
return isAscii ? unicodeScalars.first?.value : nil
}
}
// Then, set up useful extension for Strings
extension StringProtocol {
var ascii: [UInt32] {
return compactMap { $0.ascii }
}
}
// Demonstrate obtaining the value for a single character
print("H".ascii)
// Demonstrate obtaining the value for a string
print("Hello".ascii)
Python[edit]
# Single Character
print(ord('H'))
# Entire string
print([ord(char) for char in "Hello"])
