Hallo Richard!

 RM> LATIN-1 is an alias for ISO 8859-1.

Wrong.  LATIN1 is an alias for ISO 8859-1, amongst other aliases none of which
are LATIN-1.

-={ grep ISO-8859-1// /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//
module ISO-8859-1//  INTERNAL  ISO8859-1 1
module INTERNAL  ISO-8859-1//  ISO8859-1 1

The above can be verified by iana.org, and if you search their data base for
LATIN-1 will show it doesn't exist.  The closest I can find at iana.org are
ISO-8859-1-Windows-3.0-Latin-1 (alias csWindows30Latin1) and
ISO-8859-1-Windows-3.1-Latin-1 (alias csWindows31Latin1).  I did find some
unofficial claims that LATIN-1 is an alias fo CP1252 but those cannot be
verified by any credible reference.

-={ grep CP1252// /usr/lib/gconv/gconv-modules }=-
alias MS-ANSI//  CP1252//
alias WINDOWS-1252//  CP1252//
module CP1252//  INTERNAL  CP1252  1
module INTERNAL  CP1252//  CP1252  1

iana.org lists it as windows-1252 with only one alias cswindows1252.  No
mention of LATIN-1 as an alias of anything, nevermind ISO 8859-1.

Het leven is goed,
Maurice
