Yes, you are right, mutt reads the LC_* variables and is usually able to
represent characters in utf-8 if that is set by them. But in case of
problems, as I thought you might have, it may be a help to explicitly set it.

You have asked for a "display filter" setting in mutt to be able to see
the "real" character, which is a character that is part of the Unicode
Database. Even if the message you supposedly received was encoded in
ISO-8859-2, mutt, when opening the message, would convert it into Unicode
(usually, utf-8) if your LC_variables
are correctly set to use it. Or, see above, set them explicitly to be sure.
Please take note that I did not reproduce your issue. So I actually do
not know why this happens in your case. Do you have some more information?
To know, by other means, what the intended character was, in *Python* you
might use the chr() function. Given the fact that chr() works with
integers, you first have to convert the hexadecimal into an integer.
Maybe I can find some other way using just mutt's conf options.
Patience, please. :-)
