OK with s/OVERLINE/MACRON/g in the charmap.
I reviewed:
ftp://ftp.software.ibm.com/software/globalization/gcoc/attachments/CP00273.pdf
just to see if macron/overline was expected and it was. I expect what you see
there, being slightly narrower than fullwidth, is a macron.
My review shows that the *intent* of IBM273 was to stay within Latin1, and
using "OVERLINE" <U203E> goes against that intent when MACRON is fine.

This is no longer OVERLINE but MACRON, which is in theory
slightly narrower, but still fits the description of the
codepage.
