Bob,
Actually my first note on the subject only covered the surface of the
situation. I was hoping to give a simple answer. Here is the longer answer.
The official registration of code page 850 has not changed. Code page 858 is
the new code page with euro support which has been registered by IBM. It is
identical to 850 except xD5 contains the euro sign instead of the dotless i.
However our OS/2 product has decided that it would be impossible to add a new
code page in time to meet Europe's euro sign requirements, so they will
continue to support Western European languages with a code page called 850, but
it will actually be what is defined by 858 - identical to 850 but with the euro
sign at location xD5 in place of the dotless i.
Code page 850 is not much used in Turkey, instead they use 857. The feedback
so far from Turkey is that they have no concern with OS/2's approach to support
the euro.
OS/2 has fix packs for the euro support. Information can be found at:
http://ps.boulder.ibm.com/pbin-usa-ps/getobj.pl?/pdocs-usa/euro.html
If the euro fix pack has been installed on OS/2, the code page will still be
identified by 850. Applications will have to be aware of the change. One
method of checking for this is to use the OS supplied Unicode converters and
check what CP850, xD5 maps to. If it maps to U+20AC, then you know this system
has been updated for euro support.
Hope this is clear. If it's not, please take your questions directly to
nltc@ca.ibm.com, as they do all the code page registrations for IBM.

Subject: Re: Euro sign now added to CP850 and CP857
Lisa,
When i understand correctly IBM code page 850 has replaced dotless i with
the Euro sign. But what is the difference then between code page 850 and
the new code page 858?
Do you have a reference to possible ibm web pages containing code page
info related to the Euro?
Thanks,
Bob Verbrugge
