"Alexa, open Ascii Code."
"Alexa, ask Ascii Code convert apostrophe to decimal."
"Alexa, ask Ascii Code convert A as in alpha to hex."
Ask ascii code to convert any printable ascii character to a hex, decimal, octal, or binary value. Suppose you say “Convert forward slash to hex” Alexa will inform you that the hexadecimal representation of a forward slash is 2F. You may phonetic examples to clarify your request, such as “C as in charlie”.
