Thanks for the heads up.  Is this accurate?

In fact, it does.  There are two problems you might run into:

1. The editor you used may *support* Unicode, but didn't end up saving 
in it.  Go back and double-check that the file really is Unicode.  How 
you do this depends on your editor, but there's usually an option lying 
around somewhere to set a file's character encoding.

2. The other is a bit obscure: if you save your source file in Unicode 
without a Byte Order Mark and the first character is outside the ASCII 
character range, D won't be able to read it properly.

If you ''do'' have a suspicious looking first character in your source 
file, you can either stick a blank line in at the top of the file or 
save the source file again with a Byte Order Mark.

  [What's a Byte Order Mark?]

  The Byte Order Mark (or BOM) is a special character sequence at the 
beginning of any UTF text file that tells the application which UTF 
encoding is being used, and in some cases what the byte order is (ie: 
Little Endian/Big Endian.)
