How to make fonts bigger in **plain tex** math mode?

[Harald Hanche-Olsen]

This is indeed interesting.

The message, as it reached me, had a MIME content type multipart/alternative. The two parts have headers

Content-Type: text/plain; charset=UTF-8; format=flowed
Content-Transfer-Encoding: quoted-printable
and

Content-Type: text/html; charset=UTF-8
Content-Transfer-Encoding: quoted-printable
respectively. In both parts, I find several occurrences of =C2=A0, which is indeed quoted-printable-speak for a non-breaking space (U+00A0).

Interestingly, however, if I copy the code from my mail client, those non-breaking spaces turn into regular spaces. Other mail clients presumably yield the original non-breaking spaces instead.

So it appears that everybody in this little spat are both right and wrong at the same time. Please cool your tempers and take this as a lesson that email is complicated business and full of surprises.

I also detect U+A0 nonbreaking space characters in your source. (Such a character is also present after the period at the end of the first sentence in your reply to Ulrike, quoted above.)  
As sent, my message contained the following, as verified by Andrew West's wonderful  https://www.babelstone.co.uk/Unicode/whatisit.html — I can find no U+A0 (or U+00A0) anywhere.  Perhaps Mailman is taking liberties ...
