Sorry: not only does "is_utf8" miss the mark in this case, but it looks risky based on how it's described in the Encode man page: `Messing with Perl's internals The following API uses parts of Perl's internals in the current implementation. As such, they are efficient but may change. is_utf8(STRING [, CHECK]) [INTERNAL] Tests whether the UTF-8 flag is turned on in the STRING. If CHECK is true, also checks the data in STRING for being well-formed UTF-8. Returns true if successful, false otherwise.` [download] Some folks get nervous when they hear about "messing with perl's internals"...	[reply] [d/l]

This is only for the flag of the SCALAR, not for the content (or at least need to have the flag utf8 set on to check the content)! Note, I need to check if the content is UTF-8, not if the SCALAR is internally utf8. But thanks for the help. Graciliano M. P. "The creativity is the expression of the liberty".	[reply]
