Apparently not. There's a difference: Gmail now used quoted-printable, that
preserves these guillemets (as =AB and =BB) even if they are still encoded
with ISO8859-1 (without replacement by ASCII pairs of symbols).
In the previous message, Gmail thought that quoted-printable was not needed
for just these guillemets and replaced them (even if it was clearly not
needed in ISO8859-1 that has them since extremely long time, and even
before the Internet was open and emails started spreading; at that time
Google still did not even exist).
The degree sign (also in ISO 8859-1) was enough to trigger quoted-printable.
