You are right.  I have changed IndyTextEncoding(Word) to now use TIdMBCSEncoding
internally for 1252 and 437 like earlier Indy 10 versions did.

It does not.

It does exactly what its name suggests.  It implements the 7bit ASCII range
(#0 - #127) only, whereas 1252 has some 8bit values above #127.

20127 is the official codepage for ASCII, but not all OSes support 20127,
so Indy falls back to 1252 and even 437 when 20127 is not available.  It
was a mistake going the other way, though - behaving like 20127 when 1252
or 437 is requested.  A fix has been checked in.
