Thank you. Kagba In the message headers I see: Content-Type: text/plain; charset=iso-8859-1 Content-Transfer-Encoding: quoted-printable and, on inspection of the message text in the inbox folder (i.e. as it was delivered to me), I see that each and every occurrence of the _ is represented there as the three successive characters =A0, i.e. a quoted-printable code.

But since, as in the above message, it can also be interpolated into R code, this could cause unnecessary inconvenience for people who want to test the code which people post to R-help.

The quoted-printable aspect may be a red herring, since I also see that the = signs in the code are represented as =3D, as is forced in quoted-printable; but they have been rendered correctly in the text as seen (and copied). So it may just be due to substitution of _ for on the ,art of the mailer. What do others think? I don't see the underscores in that posting, but I do see this as the last line in the headers: X-MIME-Autoconverted: from quoted-printable to 8bit by fisher.stats.uwo.ca id n8898BkC031633 (fisher.stats.uwo.ca is the server that receives my email). So it looks as though whatever is doing the conversion on your system isn't doing it as well as it should. Duncan Murdoch Thanks for this. No such conversion was performed in my case: it was delivered as-is, i.e. in the original quoted-printable (QP). The destination to which it was originally delivered (manchester.ac.uk) apparently does nothing about re-encoding it. My local mailer handles the decoding and rendering of encoded content. The QP code =A0 in the source Content-Type: text/plain; charset=iso-8859-1 corresponds to Non-Breakable Space (NBSP), so presumably my mailer displays this as _ to distinguish it from the basic ASCII space (SP) (ASCII code 32, QP code =20). (Note that the QP elements =3D in the original were correctly rendered as =, so the decoding indeed took place). This still leaves open the issue that what was presumably a simple ASCII space SP when originally entered, got changed to NBSP somehow in the process of being sent! Thanks for the comment, Ted.

That's interesting. I see them using Mutt as well as with Thunderbird.
I bounced the message to a Yahoo account, and the underscores all
appear there too.
In my experience, I usually get those underscores in mail sent from
computers which are used to work in Japanese. Something to do with
the use of those characters seems to have some unintended consequences.
