Our email medium here at Profox, otoh, is plain text. It appear fine
in a browser, an email client, even emacs!

For some definition of "fine" and some definition of "plain text".

All email is encoded in some fashion.

If you use a device or a service that inserts UTF-8 or some other double-byte encoding, or HTML-like punctuation escape codes, into the email, then you don't get "plain text" when you try to read the message. And complaints about this get the response, "You should use a modern email program", while suggestions that the sender should use a plain-text-compliant email program are chuckled over and deemed "quaint", or perhaps some other less amusing term.

I am surprised to learn that RTF is a Microsoft proprietary format. It is an "open" format, and that's probably what confused me.

My encryption system can generate results that contain "unprintable" (in the technical sense, not referring to the kinds of words I sometimes use in response to relentless and mindless technological churn) characters that reside at the low end of the ASCII table. I use it to create encrypted authorization codes for separate modules in my application. I distribute the codes to users in a file that my software reads, since users can't type them. I quickly learned that I can't put those characters into a "plain text" file and have them come back out correctly, nor would they work in a .doc file. I did find that I can parse them correctly out of an RTF file FILETOSTR-ed, and my parsing code handles a couple of different RTF "standards", so that's what I use for that.

The RTF I posted to my website was created using the version of WordPad that comes with Win XP.

I don't know anyone who can't still pretty easily read an RTF file, including people using OpenOffice on a Linux box. Unlike PDF, it is accessible to blind people using screen readers. (No, Adobe's "accessibility" features don't always work, and most people don't know how to correctly OCR text being scanned into a PDF, and they get actively irritated when asked to learn). To my mind, therefore, RTF is a better universal standard for formatted text than PDF, and certainly far better than .doc (which most people don't know how, or can't be bothered (see "irritated", above), to generate from their .docx-default versions of Office).

However I do see that the RTF generated by FRX2Any is readable in Word 2010 but not in the Wordpad that comes with Windows 7.

I live in a 90 year old craftsman bungalow, ride a 28-year-old steel
bicycle and wear geeky computer clothes from the 90s. I have nothing
against quaint. Just noting it in passing.

I knew a highly-skilled and experienced computer programmer who lived full-time in a cabin whose only electricity was supplied by a single light socket dangling from his bedroom ceiling. There was no internet access. There was no cable, and no TV to consume it. There was, in fact, not even a POTS phone. In all other respects, the room resembled Van Gogh's bedroom, except it wasn't as colorful. He refused to look at a computer except his workplace. Some people like to control where their complexities and simplicities are encountered.
