This is already documented in the Elisp manual:
Many of the file functions take one or more arguments that are file
names. A file name is a string. Most of these functions expand file
name arguments using the function ‘expand-file-name’, so that ‘~’ is
handled correctly, as are relative file names (including ‘../’ and the
empty string). *Note File Name Expansion::.
