Valid ASCII is valid UTF-8. Your receiving party is mistaken.

Updated: They are probably actually seeing that your file does not have a Byte Order Mark(BOM). This mark is neither required nor recommended, but is allowed and many Windows programs add one. If you cannot convince them to understand the UTF-8 standard, you may want to look at File::BOM:

open(FH, '>:encoding(UTF-8):via(File::BOM):utf8', $filename)

April 1 Update: see also UTF-9


The intelligent reader will judge for himself. Without examining the facts fully and fairly, there is no way of knowing whether vox populi is really vox dei, or merely vox asinorum. -- Cyrus H. Gordon
