No. (ISO8859 has additional control characters in the upper half)

In a couple of places in the 2.2 code the check for unprintable
characters (thus if to output a '?') is of the form

	if ( (c < ' ') || (c > '~') ) ....

and in other places it is of the form

	if (!isascii(c)) ....

All we ask is that these both be replaced with 

	if (!isprint(c)) ...

Since those who must use the ISO8859 sets usually replace the 'ctype' macros
anyway, doing it this way allows us to use the code unchanged and those
who use ASCII don't notice the difference. The patches for this are on the
way to elm@dsync.uucp (again :-)
