Here's what I was able to decipher:
rfc1305.txt: ± (U+00B1 PLUS-MINUS SIGN) and ↑ (U+2191 UPWARDS ARROW),
rfc2166.txt: “ (U+201C LEFT DOUBLE QUOTATION MARK) and ” (U+201D RIGHT
DOUBLE QUOTATION MARK), encoded with windows-1252.
rfc2302.txt: I didn't find any non-ASCII characters in this one.
rfc2497.txt: SHY (U+00AD SOFT HYPHEN), encoded with ISO-8859-1.
rfc2557.txt: É (U+00C9 LATIN CAPITAL LETTER E WITH ACUTE), encoded with
rfc2708.txt: Some kind of apostrophe (0xC6), encoding unknown. Used to be
’ (U+2019 RIGHT SINGLE QUOTATION MARK) in
rfc2875.txt: Some kind of apostrophe (0xC6) and quotes (0xF4 and 0xF6),
encoding unknown (but the same as in rfc2708.txt). Used to be ordinary
ASCII apostrophe and quotation marks in draft-ietf-pkix-dhpop-02.txt.
rfc64.txt: µ (U+00B5 MICRO SIGN), encoded with ISO-8859-1.

rfc235.txt, rfc243.txt, rfc270.txt, rfc282.txt, rfc288.txt, rfc290.txt,
rfc292.txt, rfc303.txt: é (U+00E9 LATIN SMALL LETTER E WITH ACUTE),
encoded with ISO-8859-1 (in the RFC Online attribution notice).
rfc237.txt, rfc306.txt, rfc307.txt, rfc310.txt, rfc313.txt, rfc315.txt,
rfc316.txt, rfc317.txt, rfc323.txt, rfc327.txt, rfc367.txt, rfc369.txt: é
(U+00E9 LATIN SMALL LETTER E WITH ACUTE) and è (U+00E8 LATIN SMALL LETTER
E WITH GRAVE), encoded with ISO-8859-1 (in the RFC Online attribution
rfc441.txt: what looks like NBSP (U+00A0 NO-BREAK SPACE), encoded with
ISO-8859-1, as well as é and è in the RFC Online attribution notice.
