I'm comparing against MacIceland (on Darwin 17.5.0).  This change is good.

This one too.

Good as well.

Likewise.

The Mac keeps the international currency sign for /xdb, so we should as 
well.  The other changes are good.

Okay.

MacOS has no mapping for /xf0 and returns EILSEQ under iconv.  I think 
we should do the same.  This may require reverting the mac-is.c change, too.

Again okay.

In addition to the two discrepancies, I see this difference with your 
patch applied:

-<U03A9>     /xbd
+<U2126>     /xbd

That is, we use GREEK CAPITAL LETTER OMEGA, and MacOS uses OHM SIGN.  I 
think we should make the switch to align with MacOS.

NB: testrun.sh does not seem to force use of the non-installed gconv 
modules in the source tree.

Thanks,
