/opt/csw/lib/libiconv.so.2

On Linux I get:
echo =C3=A1 | iconv -f UTF-8 -t ASCII -; echo =F0=9F=98=81 | iconv -f UTF-8=
 -t ISO-8859-1 -
iconv: illegal input sequence at position 0
iconv: illegal input sequence at position 0
while on Solaris
echo =C3=A1 | iconv -f UTF-8 -t ASCII -; echo =F0=9F=98=81 | iconv -f UTF-8=
 -t ISO-8859-1 -
?
?
If it maps all characters which do not have representation in the destinati=
on
character set into ?, then it is useless for the test in question.=
