Re: Update of charset windows-1252, draft 3
In http://www.iana.org/assignments/character-sets it says:
"These aliases that start with "cs" contain the standard numbers along
with suggestive names in order to facilitate applications that want to
display the names in user interfaces."
And in ftp://ftp.rfc-editor.org/in-notes/rfc2978.txt it says:
"All charsets MUST be assigned a name that provides a display string
for the associated "MIBenum" value defined below."
This wording (particularly the word "display") would seem to suggest
that these cs names are not really intended to be used "on the wire".
However, putting these cs names on lines that start with "Alias:" in
the registry has caused a number of implementors to believe that they
are normal aliases:
http://msdn.microsoft.com/library/default.asp?url=/workshop/author/dhtml/reference/charsets/charset4.asp
http://lxr.mozilla.org/seamonkey/source/intl/uconv/src/charsetalias.properties
I still don't think it would be a good idea to add any "Alias:" lines
to the windows-1252 registration. One possible solution would be a new
line that starts with "MIBdisplay:" to go along with the "MIBenum:"
line.
