That's not an ASCII-value, ASCII has 8 bits at most. What you've got there is a UTF-16 Byte Order Mark: 65279 is 0xfeff (one of the well-known constants). I'd suggest you get your editor configured to write files without BOM. Maybe there's a workaround via locale settings - but I have no machine with an UTF-16 locale available. Another approach is using recode on your files before concatenating.
This question isn't really for pgsql-hackers - I'm redirecting to -general.
