Yes, that looks okay. However, I would use the IANA "cs" aliases as 
identifier names. Perhaps also use the IBM or Microsoft code page number 
as binary value, so you would get:

Tencoding = (csASCII             := 367,
             csPC850Multilingual := 850,
             csUTF8              := 65001,
             {...}
            );

Think carefully about the design. One issue will for example be that not 
every OS will support any encoding, some error handling and detection 
functionality will be necessary. The Win32 and Unix API's won't always 
cooperate with any design you think of.
