You're seeing just the function to_charlist, go back to String module for more information.

Specs

to_charlist(t()) :: charlist()

Converts a string into a charlist.

Specifically, this function takes a UTF-8 encoded binary and returns a list of its integer code points. It is similar to codepoints/1 except that the latter returns a list of code points as strings.

In case you need to work with bytes, take a look at the :binary module.

Examples

iex> String.to_charlist("æß")
'æß'
