Looking for an expression

Hello, I noticed the expression “Get a character from a code point”, so I wondered if there is an expression that, conversely, gives me the Unicode value of a character.
I looked for it but I didn’t found. Does anyone know if it exists? Thanks.

Looks like there is no get Unicode.
