Extended ASCII Viability over Tuning List

Earlier I posed the question of what percentage of tuning listers can read an
apparently-standard extended ASCII used by Netscape and Microsoft. Or more
specifically, I asked whether this:

����

looked like an umlaut-A followed by the Spanish enyeh (?) followed by the
American cent symbol, all in curly quotes.

Here's what I concluded based upon your replies:
9 people saw those characters exactly as my message described them.
2 people saw at least one character differently.
2 people looked at it using two programs, and read it successfully in one but
not the other.

Here are some relevant comments from the folks who did see those symbols
correctly:

* "I use CorelCENTRAL as jumpoff for the web and email. No MAC, 'just' a
PC."
* "Pentium II, Windows 98, Microsoft Outlook Express"
* "Your example ( ����) came through perfectly to my Mac running Netscape
navigator 3.01."
* "I'm using Eudora on a Mac."

And here are some relevant comments from the folks who did not see them as
posted:

* "I get the right characters for all, except the quotes are two tiny
rectangles pointing upward."
* "Pine [didn't work]. It uses pico as an editor."

So, my conclusion would be that, although it's probably preferable not to use
these characters routinely, when they're inconvenient avoid, it seems likely
that most tuning-listers will read them just fine.
