I don't know what you saw when you tried
C-h v describe-char-unicodedata-file RET, but what I see includes
the following: "If it is non-nil `describe-char-after' will print data
looked up from it".  Now admittedly, the link with C-x = is weak:
C-x = mentions that it calls `describe-char' if invoked with C-u,
and C-h f describe-char-after RET tells you it's an obsolete function
replaced by `describe-char'.
