Hallo Richard!   
      
    RM> "Code Page 437 MS-DOS Latin US"   
    RM> That is an alias I did not hear/read before either ;)   
      
   I looked it up on the link you provided and didn't see where they refer to   
   "Code Page 437 MS-DOS Latin US" as an alias.  In fact that page is seriously   
   lacking in any usable information.  However the onboard documentation   
   /usr/lib/gconv/gconv-modules provided by glibc states;   
      
   -={ grep 437// /usr/lib/gconv/gconv-modules }=-   
   alias	CP437//			IBM437//   
   alias	437//			IBM437//   
   alias	CSPC8CODEPAGE437//	IBM437//   
   alias	OSF100201B5//		IBM437//   
   module	IBM437//		INTERNAL		IBM437		1   
   module	INTERNAL		IBM437//		IBM437		1   
      
   According to the above CP437 is an alias for IBM437.  I checked with iana.org   
   and they confirm CP437, 437 and CSPC8CODEPAGE437 but make no mention of IBM437   
   ... or MS-DOS for that matter.  Anyhow the above information provides very   
   useful information for the DOS-think fidonet sysops who are forced to use   
   golded or msged to provide themselves a handicapped communication encoding for   
   fidonet echoareas.  Tsk, tsk.   
      
   Het leven is goed,   
   Maurice
