Hey Holger!

 HG> Ehhh, which one is what???

According to local documentation here -> glibc's /usr/lib/gconv/gconv-modules;

alias   ISO-IR-100//            ISO-8859-1//
alias   ISO_8859-1:1987//       ISO-8859-1//
alias   ISO_8859-1//            ISO-8859-1//
alias   ISO8859-1//             ISO-8859-1//
alias   ISO88591//              ISO-8859-1//
alias   LATIN1//                ISO-8859-1//
alias   L1//                    ISO-8859-1//
alias   IBM819//                ISO-8859-1//
alias   CP819//                 ISO-8859-1//
alias   CSISOLATIN1//           ISO-8859-1//
alias   8859_1//                ISO-8859-1//
alias   OSF00010001//           ISO-8859-1//

For CP1252 I see;

alias   MS-ANSI//               CP1252//
alias   WINDOWS-1252//          CP1252//

Note that neither claims LATIN-1 as an alias which can be verified by many,
many sources, including IANA.

 HG> Reading text sent for example by BP does show differently.

BP?  I don't know what that is nor do I know what codepage or encoding they
claim as native.  If indeed CP437 and it doesn't jive with well known
publications of the CP437 table of character codes then BP is wrong on it's
claim.  No?

 HG> For example the 'Æ' and 'æ' characters are typically danish

Also old English and probably some other Germanic languages ... other than
German that is.

 HG> BTW the letters 'Æ' corresponds to the letters 'ä and Ä, and the
 HG> slashed 'o' to the letters 'ö and Ö' in the other scandinavian
 HG> languages.

The most notable ones are the ø and ö characters in the word fjørd and
fjörd.  I think fjørd should be given presidence since there are more fjørds
in Norway than fjörds in Sweden I believe.  I could easily be wrong though. 
Also I think there may be more Björns than Bjørns but again I could easily be
wrong.

Bottomline is that right or wrong, this utf8 reply can do both as evidenced by
the above.  :-)

Life is good,
Maurice
