Here is the relevant entry from the IANA charset registry, current as of

Name: ISO-8859-1-Windows-3.1-Latin-1 [HP-PCL5]
MIBenum: 2001
Source: Extended ISO 8859-1 Latin-1 for Windows 3.1.
        PCL Symbol Set id: 19U
Alias: csWindows31Latin1

This charset was registered based on the Hewlett-Packard specification,
rather than Microsoft's, but it is identical to Windows Code Page 1252,
with the exact mapping of characters in the 0x80..0x9F range as Markus
cited. CP1252 was not separately registered as a IANA charset when
windows-1250, windows-1251, windows-1253..1258 were added, as it would then
have been a duplicate of MIBenum 2001. What is missing is registration
of "windows-1252" as a recognized alias of "ISO-8859-1-windows-3.1-Latin-1".
