回答1:

As Jim Garrison pointed out, you probably have a Byte Order Marker (BOM) at the start of the file. Use an editor that can view all non-printable characters and remove it.

Alternatively, you can use sed to remove it:

sed '1s/^.//' infile >> outfile

回答2:

Use another editor because it seems to be an eclipse UTF-8-BOM problem. Convert the UTF type UTF-8.

And also I note that ; First it doesn't work for me and I convert the type ANSI and after convert type to UTF-8 format. It can be a another alternative solution for you
