The encoding should not matter unless there are characters above byte 
128, because UTF-8 and the ANSI encoding are the same from 0-127.

I guess it's possible that Pg chokes if it finds a byte-order mark (BOM) 
at the start of pg_hba.conf; I haven't tested this. A BOM is optional 
for UTF-8 text but some text editors do add it, and I've run into 
software that chokes on a BOM before. Many editors do assume unknown 
text is UTF-8 if they can't identify it as some other known encoding, 
and some would add a BOM on saving in this case.

If there is a byte order mark (BOM) you'll be able to tell because the 
first three bytes of pg_hba.conf or postgresql.conf , when examined in a 
hex editor, will be 0xEF 0xBB 0xBF .
